The importance of the PhD defence reverberates throughout the academic landscape. It is not just a capstone event; it is the juncture where academic rigour meets real-world application. The defence is the litmus test of a researcher’s ability to articulate, defend, and contextualize their work—an evaluation that extends beyond the pages of a dissertation.

Beyond its evaluative nature, the defence serves as a rite of passage, validating the years of dedication, perseverance, and intellectual rigour invested in the research endeavour. Success in the defence is a testament to the candidate’s mastery of their subject matter and the originality and impact of their contributions to the academic community.

Furthermore, a successful defence paves the way for future contributions, positioning the scholar as a recognized authority in their field. The defence is not just an endpoint; it is a launchpad, propelling researchers into the next phase of their academic journey as they continue to shape and redefine the boundaries of knowledge.

In essence, the PhD defence is more than a ceremonial checkpoint—it is a transformative experience that validates the intellectual journey, underscores the significance of scholarly contributions, and sets the stage for a continued legacy of academic excellence. As we navigate the intricacies of this process, we invite you to explore the multifaceted dimensions that make the PhD defence an indispensable chapter in the narrative of academic achievement.

What is a PhD Defence?

At its core, a PhD defence is a rigorous and comprehensive examination that marks the culmination of a doctoral candidate’s research journey. It is an essential component of the doctoral process in which the candidate is required to defend their dissertation before a committee of experts in the field. The defence serves multiple purposes, acting as both a showcase of the candidate’s work and an evaluative measure of their understanding, critical thinking, and contributions to the academic domain.

The primary goals of a PhD defence include:

• Presentation of Research: The candidate presents the key findings, methodology, and significance of their research.
• Demonstration of Mastery: The defence assesses the candidate’s depth of understanding, mastery of the subject matter, and ability to engage in scholarly discourse.
• Critical Examination: Committee members rigorously question the candidate, challenging assumptions, testing methodologies, and probing the boundaries of the research.
• Validation of Originality: The defence validates the originality and contribution of the candidate’s work to the existing body of knowledge.

The PhD defence often takes the form of an oral examination, commonly referred to as the viva voce. This oral component adds a dynamic and interactive dimension to the evaluation process. Key elements of the oral examination include:

• Presentation: The candidate typically begins with a formal presentation, summarizing the dissertation’s main components, methodology, and findings. This presentation is an opportunity to showcase the significance and novelty of the research.
• Questioning and Discussion: Following the presentation, the candidate engages in a thorough questioning session with the examination committee. Committee members explore various aspects of the research, challenging the candidates to articulate their rationale, defend their conclusions, and respond to critiques.
• Defence of Methodology: The candidate is often required to defend the chosen research methodology, demonstrating its appropriateness, rigour, and contribution to the field.
• Evaluation of Contributions: Committee members assess the originality and impact of the candidate’s contributions to the academic discipline, seeking to understand how the research advances existing knowledge.

The oral examination is not a mere formality; it is a dynamic exchange that tests the candidate’s intellectual acumen, research skills, and capacity to contribute meaningfully to the scholarly community.

In essence, the PhD defence is a comprehensive and interactive evaluation that encapsulates the essence of a candidate’s research journey, demanding a synthesis of knowledge, clarity of expression, and the ability to navigate the complexities of academic inquiry. As we delve into the specifics of the defence process, we will unravel the layers of preparation and skill required to navigate this transformative academic milestone.

How Long is a PhD Defence?

The duration of a PhD defence can vary widely, but it typically ranges from two to three hours. This time frame encompasses the candidate’s presentation of their research, questioning and discussions with the examination committee, and any additional deliberations or decisions by the committee. However, it’s essential to note that this is a general guideline, and actual defence durations may vary based on numerous factors.

• Sciences and Engineering: Defenses in these fields might lean towards the shorter end of the spectrum, often around two hours. The focus is often on the methodology, results, and technical aspects.
• Humanities and Social Sciences: Given the theoretical and interpretive nature of research in these fields, defences might extend closer to three hours or more. Discussions may delve into philosophical underpinnings and nuanced interpretations.
• Simple vs. Complex Studies: The complexity of the research itself plays a role. Elaborate experiments, extensive datasets, or intricate theoretical frameworks may necessitate a more extended defence.
• Number of Committee Members: A larger committee or one with diverse expertise may lead to more extensive discussions and varied perspectives, potentially elongating the defence.
• Committee Engagement: The level of engagement and probing by committee members can influence the overall duration. In-depth discussions or debates may extend the defence time.
• Cultural Norms: In some countries, the oral defence might be more ceremonial, with less emphasis on intense questioning. In others, a rigorous and extended defence might be the norm.
• Evaluation Practices: Different academic systems have varying evaluation criteria, which can impact the duration of the defence.
• Institutional Guidelines: Some institutions may have specific guidelines on defence durations, influencing the overall time allotted for the process.

Candidates should be well-prepared for a defence of any duration. Adequate preparation not only involves a concise presentation of the research but also anticipates potential questions and engages in thoughtful discussions. Additionally, candidates should be flexible and responsive to the dynamics of the defense, adapting to the pace set by the committee.

Success Factors in a PhD Defence

• Successful defence begins with a deep and comprehensive understanding of the research. Candidates should be well-versed in every aspect of their study, from the theoretical framework to the methodology and findings.

• Comprehensive preparation is the cornerstone of success. Candidates should dedicate ample time to understanding every facet of their research, conducting mock defences, and seeking feedback.
• Identify potential weaknesses in the research and address them proactively. Being aware of limitations and articulating plans for addressing them in future work demonstrates foresight.
• Engage with mentors, peers, or advisors before the defence. Solicit constructive feedback on both the content and delivery of the presentation to refine and strengthen the defence.
• Develop strategies to manage stress and nervousness. Techniques such as mindfulness, deep breathing, or visualization can be effective in maintaining composure during the defence.
• Conduct a pre-defense review of all materials, ensuring that the presentation aligns with the dissertation and that visual aids are clear and supportive.
• Approach the defence with an open and reflective attitude. Embrace critique as an opportunity for improvement rather than as a personal affront.
• Clarify expectations with the examination committee beforehand. Understanding the committee’s focus areas and preferences can guide preparation efforts.
• In the event of failure, candidates should approach the situation with resilience. Seek feedback from the committee, understand the reasons for the outcome, and use the experience as a springboard for improvement.

In summary, while the prospect of failing a PhD defence is uncommon, acknowledging its possibility and taking proactive steps to mitigate risks are crucial elements of a well-rounded defence strategy. By addressing common failure factors through thorough preparation, openness to critique, and a resilient attitude, candidates can increase their chances of a successful defence outcome.

PhD Defense or Defence?

• The choice between “defense” and “defence” is primarily a matter of British English versus American English spelling conventions. “Defense” is the preferred spelling in American English, while “defence” is the British English spelling.
• In the global academic community, both spellings are generally understood and accepted. However, the choice of spelling may be influenced by the academic institution’s language conventions or the preferences of individual scholars.

Defending Your Dissertation: A Guide

Written by Luke Wink-Moran | Photo by insta_photos

Dissertation defenses are daunting, and no wonder; it’s not a “dissertation discussion,” or a “dissertation dialogue.” The name alone implies that the dissertation you’ve spent the last x number of years working on is subject to attack. And if you don’t feel trepidation for semantic reasons, you might be nervous because you don’t know what to expect. Our imaginations are great at making The Unknown scarier than reality. The good news is that you’ll find in this newsletter article experts who can shed light on what dissertations defenses are really like, and what you can do to prepare for them.

The first thing you should know is that your defense has already begun. It started the minute you began working on your dissertation— maybe even in some of the classes you took beforehand that helped you formulate your ideas. This, according to Dr. Celeste Atkins, is why it’s so important to identify a good mentor early in graduate school.

“To me,” noted Dr. Atkins, who wrote her dissertation on how sociology faculty from traditionally marginalized backgrounds teach about privilege and inequality, “the most important part of the doctoral journey was finding an advisor who understood and supported what I wanted from my education and who was willing to challenge me and push me, while not delaying me.  I would encourage future PhDs to really take the time to get to know the faculty before choosing an advisor and to make sure that the members of their committee work well together.”

Your advisor will be the one who helps you refine arguments and strengthen your work so that by the time it reaches your dissertation committee, it’s ready. Next comes the writing process, which many students have said was the hardest part of their PhD. I’ve included this section on the writing process because this is where you’ll create all the material you’ll present during your defense, so it’s important to navigate it successfully. The writing process is intellectually grueling, it eats time and energy, and it’s where many students find themselves paddling frantically to avoid languishing in the “All-But-Dissertation” doldrums. The writing process is also likely to encroach on other parts of your life. For instance, Dr. Cynthia Trejo wrote her dissertation on college preparation for Latin American students while caring for a twelve-year-old, two adult children, and her aging parents—in the middle of a pandemic. When I asked Dr. Trejo how she did this, she replied:

“I don’t take the privilege of education for granted. My son knew I got up at 4:00 a.m. every morning, even on weekends, even on holidays; and it’s a blessing that he’s seen that work ethic and that dedication and the end result.”

Importantly, Dr. Trejo also exercised regularly and joined several online writing groups at UArizona. She mobilized her support network— her partner, parents, and even friends from high school to help care for her son.

The challenges you face during the writing process can vary by discipline. Jessika Iwanski is an MD/PhD student who in 2022 defended her dissertation on genetic mutations in sarcomeric proteins that lead to severe, neonatal dilated cardiomyopathy. She described her writing experience as “an intricate process of balancing many things at once with a deadline (defense day) that seems to be creeping up faster and faster— finishing up experiments, drafting the dissertation, preparing your presentation, filling out all the necessary documents for your defense and also, for MD/PhD students, beginning to reintegrate into the clinical world (reviewing your clinical knowledge and skill sets)!”

But no matter what your unique challenges are, writing a dissertation can take a toll on your mental health. Almost every student I spoke with said they saw a therapist and found their sessions enormously helpful. They also looked to the people in their lives for support. Dr. Betsy Labiner, who wrote her dissertation on Interiority, Truth, and Violence in Early Modern Drama, recommended, “Keep your loved ones close! This is so hard – the dissertation lends itself to isolation, especially in the final stages. Plus, a huge number of your family and friends simply won’t understand what you’re going through. But they love you and want to help and are great for getting you out of your head and into a space where you can enjoy life even when you feel like your dissertation is a flaming heap of trash.”

While you might sometimes feel like your dissertation is a flaming heap of trash, remember: a) no it’s not, you brilliant scholar, and b) the best dissertations aren’t necessarily perfect dissertations. According to Dr. Trejo, “The best dissertation is a done dissertation.” So don’t get hung up on perfecting every detail of your work. Think of your dissertation as a long-form assignment that you need to finish in order to move onto the next stage of your career. Many students continue revising after graduation and submit their work for publication or other professional objectives.

When you do finish writing your dissertation, it’s time to schedule your defense and invite friends and family to the part of the exam that’s open to the public. When that moment comes, how do you prepare to present your work and field questions about it?

“I reread my dissertation in full in one sitting,” said Dr. Labiner. “During all my time writing it, I’d never read more than one complete chapter at a time! It was a huge confidence boost to read my work in full and realize that I had produced a compelling, engaging, original argument.”

There are many other ways to prepare: create presentation slides and practice presenting them to friends or alone; think of questions you might be asked and answer them; think about what you want to wear or where you might want to sit (if you’re presenting on Zoom) that might give you a confidence boost. Iwanksi practiced presenting with her mentor and reviewed current papers to anticipate what questions her committee might ask.  If you want to really get in the zone, you can emulate Dr. Labiner and do a full dress rehearsal on Zoom the day before your defense.

But no matter what you do, you’ll still be nervous:

“I had a sense of the logistics, the timing, and so on, but I didn’t really have clear expectations outside of the structure. It was a sort of nebulous three hours in which I expected to be nauseatingly terrified,” recalled Dr. Labiner.

“I expected it to be terrifying, with lots of difficult questions and constructive criticism/comments given,” agreed Iwanski.

“I expected it to be very scary,” said Dr. Trejo.

“I expected it to be like I was on trial, and I’d have to defend myself and prove I deserved a PhD,” said Dr Atkins.

And, eventually, inexorably, it will be time to present.  

“It was actually very enjoyable” said Iwanski. “It was more of a celebration of years of work put into this project—not only by me but by my mentor, colleagues, lab members and collaborators! I felt very supported by all my committee members and, rather than it being a rapid fire of questions, it was more of a scientific discussion amongst colleagues who are passionate about heart disease and muscle biology.”

“I was anxious right when I logged on to the Zoom call for it,” said Dr. Labiner, “but I was blown away by the number of family and friends that showed up to support me. I had invited a lot of people who I didn’t at all think would come, but every single person I invited was there! Having about 40 guests – many of them joining from different states and several from different countries! – made me feel so loved and celebrated that my nerves were steadied very quickly. It also helped me go into ‘teaching mode’ about my work, so it felt like getting to lead a seminar on my most favorite literature.”

“In reality, my dissertation defense was similar to presenting at an academic conference,” said Dr. Atkins. “I went over my research in a practiced and organized way, and I fielded questions from the audience.

“It was a celebration and an important benchmark for me,” said Dr. Trejo. “It was a pretty happy day. Like the punctuation at the end of your sentence: this sentence is done; this journey is done. You can start the next sentence.”

How to prepare an excellent thesis defense

What is a thesis defense?

How long is a thesis defense, what happens at a thesis defense, your presentation, questions from the committee, 6 tips to help you prepare for your thesis defense, 1. anticipate questions and prepare for them, 2. dress for success, 3. ask for help, as needed, 4. have a backup plan, 5. prepare for the possibility that you might not know an answer, 6. de-stress before, during, and after, frequently asked questions about preparing an excellent thesis defense, related articles.

If you're about to complete, or have ever completed a graduate degree, you have most likely come across the term "thesis defense." In many countries, to finish a graduate degree, you have to write a thesis .

A thesis is a large paper, or multi-chapter work, based on a topic relating to your field of study.

Once you hand in your thesis, you will be assigned a date to defend your work. Your thesis defense meeting usually consists of you and a committee of two or more professors working in your program. It may also include other people, like professionals from other colleges or those who are working in your field.

During your thesis defense, you will be asked questions about your work. The main purpose of your thesis defense is for the committee to make sure that you actually understand your field and focus area.

The questions are usually open-ended and require the student to think critically about their work. By the time of your thesis defense, your paper has already been evaluated. The questions asked are not designed so that you actually have to aggressively "defend" your work; often, your thesis defense is more of a formality required so that you can get your degree.

• Check with your department about requirements and timing.
• Re-read your thesis.
• Anticipate questions and prepare for them.
• Create a back-up plan to deal with technology hiccups.
• Plan de-stressing activities both before, and after, your defense.

How long your oral thesis defense is depends largely on the institution and requirements of your degree. It is best to consult your department or institution about this. In general, a thesis defense may take only 20 minutes, but it may also take two hours or more. The length also depends on how much time is allocated to the presentation and questioning part.

Tip: Check with your department or institution as soon as possible to determine the approved length for a thesis defense.

First of all, be aware that a thesis defense varies from country to country. This is just a general overview, but a thesis defense can take many different formats. Some are closed, others are public defenses. Some take place with two committee members, some with more examiners.

The same goes for the length of your thesis defense, as mentioned above. The most important first step for you is to clarify with your department what the structure of your thesis defense will look like. In general, your thesis defense will include:

• your presentation of around 20-30 minutes
• questions from the committee
• questions from the audience (if the defense is public and the department allows it)

You might have to give a presentation, often with Powerpoint, Google slides, or Keynote slides. Make sure to prepare an appropriate amount of slides. A general rule is to use about 10 slides for a 20-minute presentation.

But that also depends on your specific topic and the way you present. The good news is that there will be plenty of time ahead of your thesis defense to prepare your slides and practice your presentation alone and in front of friends or family.

Tip: Practice delivering your thesis presentation in front of family, friends, or colleagues.

You can prepare your slides by using information from your thesis' first chapter (the overview of your thesis) as a framework or outline. Substantive information in your thesis should correspond with your slides.

Make sure your slides are of good quality— both in terms of the integrity of the information and the appearance. If you need more help with how to prepare your presentation slides, both the ASQ Higher Education Brief and James Hayton have good guidelines on the topic.

The committee will ask questions about your work after you finish your presentation. The questions will most likely be about the core content of your thesis, such as what you learned from the study you conducted. They may also ask you to summarize certain findings and to discuss how your work will contribute to the existing body of knowledge.

Tip: Read your entire thesis in preparation of the questions, so you have a refreshed perspective on your work.

While you are preparing, you can create a list of possible questions and try to answer them. You can foresee many of the questions you will get by simply spending some time rereading your thesis.

Here are a few tips on how to prepare for your thesis defense:

You can absolutely prepare for most of the questions you will be asked. Read through your thesis and while you're reading it, create a list of possible questions. In addition, since you will know who will be on the committee, look at the academic expertise of the committee members. In what areas would they most likely be focused?

If possible, sit at other thesis defenses with these committee members to get a feel for how they ask and what they ask. As a graduate student, you should generally be adept at anticipating test questions, so use this advantage to gather as much information as possible before your thesis defense meeting.

Your thesis defense is a formal event, often the entire department or university is invited to participate. It signals a critical rite of passage for graduate students and faculty who have supported them throughout a long and challenging process.

While most universities don't have specific rules on how to dress for that event, do regard it with dignity and respect. This one might be a no-brainer, but know that you should dress as if you were on a job interview or delivering a paper at a conference.

It might help you deal with your stress before your thesis defense to entrust someone with the smaller but important responsibilities of your defense well ahead of schedule. This trusted person could be responsible for:

• preparing the room of the day of defense
• setting up equipment for the presentation
• preparing and distributing handouts

Technology is unpredictable. Life is too. There are no guarantees that your Powerpoint presentation will work at all or look the way it is supposed to on the big screen. We've all been there. Make sure to have a plan B for these situations. Handouts can help when technology fails, and an additional clean shirt can save the day if you have a spill.

One of the scariest aspects of the defense is the possibility of being asked a question you can't answer. While you can prepare for some questions, you can never know exactly what the committee will ask.

There will always be gaps in your knowledge. But your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. You are not expected to know everything.

James Hayton writes on his blog that examiners will sometimes even ask questions they don't know the answer to, out of curiosity, or because they want to see how you think. While it is ok sometimes to just say "I don't know", he advises to try something like "I don't know, but I would think [...] because of x and y, but you would need to do [...] in order to find out.” This shows that you have the ability to think as an academic.

You will be nervous. But your examiners will expect you to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions, for example. Dora Farkas at finishyourthesis.com notes that it’s a myth that thesis committees are out to get you.

Two common symptoms of being nervous are talking really fast and nervous laughs. Try to slow yourself down and take a deep breath. Remember what feels like hours to you are just a few seconds in real life.

• Try meditational breathing right before your defense.
• Get plenty of exercise and sleep in the weeks prior to your defense.
• Have your clothes or other items you need ready to go the night before.
• During your defense, allow yourself to process each question before answering.
• Go to dinner with friends and family, or to a fun activity like mini-golf, after your defense.

Allow yourself to process each question, respond to it, and stop talking once you have responded. While a smile can often help dissolve a difficult situation, remember that nervous laughs can be irritating for your audience.

We all make mistakes and your thesis defense will not be perfect. However, careful preparation, mindfulness, and confidence can help you feel less stressful both before, and during, your defense.

Finally, consider planning something fun that you can look forward to after your defense.

It is completely normal to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions for example if needed. Slow yourself down, and take a deep breath.

Your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. James Hayton writes on his blog that it is ok sometimes to just say "I don't know", but he advises to try something like "I don't know, but I would think [...] because of x and y, you would need to do [...] in order to find out".

Your Powerpoint presentation can get stuck or not look the way it is supposed to do on the big screen. It can happen and your supervisors know it. In general, handouts can always save the day when technology fails.

• Dress for success.
• Ask for help setting up.
• Have a backup plan (in case technology fails you).
• Deal with your nerves.

The Last Big Hurdle: How to Prepare for a Successful PhD Defence

It’s the moment almost everyone who completes a PhD both dreads and looks ahead to for years—the defence. It signals a major achievement, but in people’s imaginations, it can seem like the stuff of nightmares… standing frozen in front of everyone, unable to answer a tricky question posed by a committee member and feeling like you must look incompetent. The format of a doctoral defence varies from field to field, but the worst fears of the candidates remain largely the same. Though most people know it probably won’t go so badly, the open-ended-ness can certainly be intimidating- you’re up there alone in front of a panel of experts who get to ask you whatever they’d like, and you may have to deliver your answers in front of an audience of your peers. There are few experiences in academic life more geared to be stressful for the person at the centre of them.

It doesn’t have to be that bad. I spent the weeks leading up to my PhD defence in a state of near panic, but I can honestly say that once it actually got underway, I sort of enjoyed it. You’re the star of the show and get to walk your peers through the finer points of your research. It can be a really invigorating experience. So let’s try to break this down into bite-sized chunks and look at strategies and tips for making your defence an event you might actually look back fondly on.

What the committee wants

Let’s start with what the committee is actually looking for. They want to see a firm grasp of the subject matter, an understanding of the implications of the work, and the ability to see weaknesses in the methodology and possible routes to take for future work. This means creating a presentation that gives a clear, logical overview of your topic, the question you’re addressing, what you did, your results and conclusions, and where the research can go from here. Remember, your jury members are not out to get you. The questions you receive from them will generally fall under one of three headings- those that test your subject knowledge, those that clarify a confusing point, and those that arise from genuine curiosity. If your presentation does a good job of conveying your knowledge of your topic, you can expect more questions from the second and third categories, allowing you to think of the defense more as a conversation amongst experts than a test from on high.

How to prepare

Practice is obviously very important here. Once you’ve put your talk together, find a trusted friend or mentor (ideally, several of them) who knows your field to go through it with you. They can both help you to pare down unnecessary parts and point out logical leaps you may not have noticed because you’re so close to the subject matter. You also want this to be a person who will ask you tough questions and try to spot holes in your reasoning, so choose your test audience carefully. It can be tempting to spend a lot of time obsessing over your slides, trying to make them perfect, but there’s a lot of studying you’ll need to do to be ready for more tangential questions, so don’t lose too much time this way.

Even though you have lived and breathed your thesis topic for years, it’s a good idea to give your thesis a complete re-read just to make sure you really know what’s in there. It may have been months since you finished writing it, and parts may have gotten a little fuzzy since then. Make sure you know why you used the methodology that you did, be able to justify any conclusions you’ve made, and if there are mistakes, admit them openly at the defence and be able to talk about what you should have done differently—the committee isn’t looking for perfection, they’re looking for clear thinking and thorough consideration of methodology.

This is also a good time to review important topics that are peripheral to your work; this will allow you to answer some of the questions designed to test the limits of your broader knowledge of your field. One of the best pieces of defence preparation advice I’ve ever heard is to find out what each of your committee members’ professional interests are, and do a bit of reading on those topics. There’s a very good chance that they’ll ask you something that’s related to their own work, because that’s familiar ground to them, and you may be able to anticipate these questions this way.

Finally, though it’s less and less of a problem as technology improves, you’ll want to make very sure ahead of time that all your presentation gear works and connects properly to the display equipment in the room where your defence will be. No one wants to be running around at the last moment looking for a dongle they didn’t think they needed, or have their laptop’s battery run out partway through the defence. Check that your slides look the same way on the projection screen as they do on your computer- not cut off or too dark. It also doesn’t hurt just to spend time in the room in which you’ll be presenting, to get a feel for the place and see where everything will be positioned.

Common questions and ideas to think about

• What makes your project original, and how does it answer a previously unanswered question? What have you contributed to the body of knowledge on this topic?
• Why was this question important to ask? Why do we care about what your findings reveal? (Hint: “Just for the sake of knowing” is not an acceptable answer here.)
• Did the focus of your project change over its course? If so, explain how and why.

Methodology

• Why did you choose your methodological approach (including your statistical analyses)? Why is it superior to or more appropriate than all other methodologies?
• Talk about the difficulties you experienced with your methodology and how you addressed them.
• What are the limitations of your study design/methodology?
• Explain how your data represent an appropriate source of measurement to address your question.
• Is the amount of data gathered sufficient to address your question? Why or why not?
• If you could do it again with unlimited time and funds, how would your methodology change?

Conclusions

• What would you say is the most important “take-away” message of your work?
• Does your work have wider implications for other disciplines in your field?
• How do your conclusions support or contradict the existing literature?
• Are there alternative ways your data could have been interpreted?
• Speculate about what broader implications your research could have, but which aren’t addressed by your data, or were outside the scope of your project.
• If you were to continue on with this area of research, what would you do next to further your results? Is there a closely related “spin-off” question that needs to be answered?
• Propose an experimental design to test this related question. What results might you expect to see?
• Where do you think this field of study is headed in the next five to ten years?

Tips, tricks, and stress management

• Practice the first few minutes of your talk until you can do it on ‘autopilot’; this will give you a bit of time to relax into your presentation, get your thoughts in order, and begin talking more confidently.
• If your defence is open to the public, ask a few supportive friends or colleagues to sit where you can easily make eye contact while you’re talking. Seeing a friendly, smiling face can be encouraging and help you to relax.
• Don’t forget to review the newest literature in the weeks leading up to your defence—one or more important papers may have been published in your field since you wrote your thesis, and you’ll want to know about them.
• Have a hard copy of your thesis on hand during the defence. It’s much faster to flip to a physical page when asked about a particular section of the text. If this really isn’t for you, be sure you have a quick way to move through pages on your computer.
• Eat and drink the same things you normally would on the day of your defence. Your stomach may be extra sensitive in response to the stress, and you don’t want to surprise it with anything new. And go easy on the caffeine… jittery-ness will not help you to manage your stress!
• Try to let your enthusiasm for your subject matter show; your audience will feel more positive about your talk if they can see that you really find the work fascinating.
• It’s fine to take a moment to think about your answer before responding. The silence isn’t as long or as deafening as you think it is. And if you don’t know, just admit you don’t know—it’s okay to not know everything.
• Dress well, but comfortably, and try to project confidence. If you can speak to your committee as a group of your peers, it will reflect well on your growth as a scientist in training- and demonstrate you are someone who deserves to be awarded their doctorate.
• Don’t forget to publicly thank your advisor, your committee, and any other key people involved with your project for their time commitment and investment in your career.
• When planning post-defence festivities, be aware that you may be more tired, both mentally and emotionally, than you expected. Don’t ask too much of yourself in the hours following the event.

A bit of encouragement

Above all, there are two things you need to remember while preparing for your defence. First, your advisor and committee would not have allowed you to proceed to this point if they didn’t think you were ready. They want to see you succeed and, altruism aside, it would reflect badly on them as well if you were to fail. Trust that they’ve made the right decision. Second, after years of delving into your little corner of the scientific world, no one knows your thesis topic better than you do—not even your committee. Marshall your facts and feel confident in knowing that on this topic, you’re the world expert.

Once you have submitted your dissertation, you may be asked to do a defence of your dissertation. This could be in the form of an oral presentation, a poster presentation of your findings, or you could be invited to a viva voce. Vivas, as they are usually known, are particularly common for research degrees such as MPhils or PhDs and are essentially a verbal defence of your thesis that is conducted in an interview style format. At a minimum, the viva is a way of checking you authored the thesis yourself and understand the detail, but it is also an opportunity to discuss your research findings and interpretations in depth with experts. Preparation is key for defending your thesis in a viva or a presentation format. With a bit of groundwork, you could even enjoy the discussion, after all the thesis is the culmination of all your hard work, and no one knows it better than you.

The top 10 thesis defense questions (+ how to prepare strong answers)

Crafting a thesis is significant, but defending it often feels like the ultimate test. While nerve-wracking, proper preparation can make it manageable. Prepare for your thesis defense with insights on the top questions you can expect, including strategies for answering convincingly.

Mastering the thesis defense: cultivate a success mindset

Question 1: why did you choose this particular topic for your research, question 2: how does your research contribute to the existing body of knowledge, question 3: what are the key findings of your research, question 4: can you defend your research methodology, question 5: how did you analyze the data and what challenges did you encounter, question 6: what theoretical frameworks or references underpin your research, question 7: how did you address ethical considerations in your research, question 8: in what ways does your research contribute to the field, question 9: how did you ensure your research was free from bias, question 10: where can future research go from here.

Nurturing a success mindset for your defense is pivotal. This means adopting a mental outlook geared towards achieving favorable outcomes during your thesis defense. To truly excel in this pivotal academic moment, it’s imperative to cultivate both confidence and composure.

Confidence enables you to present your research with conviction, while composure allows you to navigate any challenges with grace and clarity.

Remember, you know your thesis best, so trust in your expertise.

In essence, a success mindset encompasses the belief in your abilities, coupled with the ability to remain calm and focused under pressure.

Stay composed and focused, relying on your thorough preparation. If you encounter a question you can’t answer, gracefully guide the conversation back to familiar topics.

Use strategic responses when needed. For example, if a question goes beyond your thesis scope, acknowledge its relevance but steer back to your focused areas. Similarly, if you’re unfamiliar with a theory or literature, admit it but offer related insights or perspectives.

By embracing these principles and staying confident and adaptable, you’ll navigate your thesis defense with ease.

This question delves into the origins of your academic journey, aiming to understand not just what you studied, but the underlying motivations and processes that drove your exploration. It’s not merely about the superficial aspects of your research, but rather about the deeper intellectual curiosity that ignited your quest.

To effectively respond, take the opportunity to elaborate on the intricacies of your journey. Begin by unpacking the specific interests or questions that sparked your intellectual curiosity in the subject matter. What events, experiences, or influences led you to delve into this particular area of study? Providing an anecdote or example that vividly illustrates the genesis of your scholarly pursuit can be helpful.

Moreover, discuss the gaps you identified in the existing literature that motivated you to contribute to your field. What deficiencies or unanswered questions did you observe? How did these gaps inspire you to embark on your research journey with the aim of filling these voids?

Dissertation proposal defense: 12 tips for effective preparation, published by steve tippins on may 11, 2020 may 11, 2020.

Last Updated on: 22nd May 2024, 04:08 am

The dissertation proposal defense is a nerve-wracking time for even the most hardened of doctoral students.

Even a pirate (writing his dissertation on effective cutlass techniques), will quake a bit in his boots before delivering his dissertation proposal defense.

However, it doesn’t need to be a stressful time. 

As a longtime Dissertation Committee Chair and committee member, I’ve overseen more dissertation proposal defenses than I can count. I’ve also helped students through the process as a coach . 

If you follow these tips for preparing and delivering your presentation, you shouldn’t have any problem passing your proposal defense.

Dissertation Proposal Defense Tips

Preparing for your Dissertation Proposal Defense

1. anticipate questions.  .

In your presentation, try to answer all of the questions you expect your committee to ask. That way, you control the material. Your committee will be more satisfied with your preparation and understanding and it will be less likely that you have to answer questions that you aren’t prepared for.

2. Look for Weaknesses.  

If there are potential weaknesses (in your study, proposal, or presentation), address them ahead of time. Ask peers or mentors to review your proposal or presentation for weaknesses. Look at it yourself with a critical eye. Even if you’re not able to eliminate a weakness, take steps to address it as best you can so that your committee can be confident that you’re aware of it and able to handle it.

3. Practice.  

Ideally, you would practice with someone who has been a committee member before. They’ll point out the types of questions they would see your committee asking, so you can prepare for those. I can’t understate the value of having this kind of feedback beforehand so that you can properly prepare. I offer this service as part of my dissertation coaching package .

4. Avoid Wordiness on PowerPoint Slides . 

Most dissertation proposal defenses have PowerPoints. Don’t put too many words on the slides! People will start reading the slides instead of paying attention to you. Then they’re off somewhere else which will produce questions that you’ve already answered when they weren’t paying attention.

5. Be Able to Pronounce the Words Correctly. 

This might sound obvious, but as a dissertation committee member , I’ve heard far too many students struggle through pronunciations of important terminology. This is probably because, up until this point, they’ve only read them and not spoken them out loud. 

However, it gives the committee the impression that they don’t know what they’re talking about. Make sure you can properly pronounce all the words you plan on using (like “phenomenological” and “anthropomorphism,”). 

6. Watch Recordings of Previous Defenses.  

Some schools have recordings of previous defenses. Listen to one or two. See how the procedure goes. Even if it’s not anything in your discipline, it will still help you get familiar with the procedure itself, which will help you be more comfortable when the time comes.

During your Dissertation Proposal Defense:

7. breathe . .

I’ve seen way too many people try to do their dissertation proposal defense seemingly in one breath. Give your committee time to hear and understand what you’re saying. Remember to leave some moments of silence to allow your audience to digest what you say. Also remember that one second of actual time feels like about thirty minutes to someone who’s giving an important presentation. Breathe. 

8. Remember: They Want to Pass You.  

If you’ve gotten to the point where your committee has scheduled a dissertation proposal defense for you, that means they believe that you can pass it. They want to pass you. Remember that. 

They’re not out to screw you, they’re not out for “gotchas.” They’re saying, “we believe you’re ready, show us that’s true.” While they will be rigorous in their evaluation because they have a responsibility to make sure that they don’t allow you to move forward until you are ready to, it’s helpful to remember that they believe you can pass. 

9. Answer the Question, No More.  

When committee members ask questions, answer only the question–don’t give them anything more than that. Imagine that you’re a witness in a courtroom (or don’t if that makes you more nervous). Committee members value direct, relevant answers and often find tangents irrelevant and frustrating.

10. Dialogue With Your Committee.  

If the committee disagrees with something you said, it can be a discussion. You don’t need to just roll over and say “Yes, you’re right. I made a mistake and I’m very bad.” That’s not what your committee wants to hear, either. 

A much better response would be, “I hear what you’re saying, however, this is the reason I’m going in this other direction. What do you think about that?” So you’re beginning to engage in discussions as a scholar. Your committee will be impressed by your ability to think critically and your willingness to engage in dialogue.

However, do not make it adversarial. It’s incredibly important to be respectful in these conversations. After all, your committee members have significant control over your life for as long as you’re writing your dissertation.

11. Make Life Easy for Your Committee.  

It’s always good to send your committee members a copy of your PowerPoint presentation and the most recent copy of your proposal the day before the defense. They likely already have a copy, but when in doubt, make their lives easier. It doesn’t cost you anything. Someone might accidentally have an old copy, or might take them some time to find the copy they have. You want their life to be as easy as possible so they can focus on moving you forward.

12. Pay Attention to Time. 

Ask your Chair (in the preparation stage) how long you have to make your presentation. It’s extraordinarily important to stay within this timeframe. If you’re told 25 minutes but you take 50 minutes, committee members are predisposed to say “why isn’t this person better prepared, and why are they wasting my time?”

Likewise, if you run through a 30-minute presentation in ten minutes (nervousness can sometimes lead to very fast talking–that’s why it’s important to practice beforehand), your committee will be wondering why you didn’t use the whole time that was allotted to you. And you’ll likely have to field a lot of questions you weren’t prepared for.

Dissertation Proposal Defense Summary

As long as you prepare properly, your dissertation proposal defense should be nothing to worry about. Your committee thinks you’re ready: all you have to do is show them you’re right.

Top 7 tips for your defense presentation

1. show why your study is important, remember, your audience is your committee members, researchers in other fields, and even the general public. you want to convince all of them why you deserve a ph.d. degree. you need to talk about why your study is important to the world. in the engineering field, you also need to talk about how your study is useful. try to discuss why current practice is problematic or not good enough, what needs to be solved, and what the potential benefits will be. , see how dr. posen and dr. malings explained the importance of their studies..

• Carl Malings Defense Slides with Notes
• I. Daniel Posen Defense Slides with Notes

2. Emphasize YOUR contribution 

Having a ph.d. means that you have made some novel contributions to the grand field. this is about you and your research. you need to keep emphasizing your contributions throughout your presentation. after talking about what needs to be solved, try to focus on emphasizing the novelty of your work. what problems can be solved using your research outcomes what breakthroughs have you made to the field why are your methods and outcomes outstanding you need to incorporate answers to these questions in your presentation. , be clear what your contributions are in the introduction section; separate what was done by others and what was done by you. , 3. connect your projects into a whole piece of work, you might have been doing multiple projects that are not strongly connected. to figure out how to connect them into a whole piece, use visualizations such as flow charts to convince your audience. the two slides below are two examples. in the first slide, which was presented in the introduction section, the presenter used a flow diagram to show the connection between the three projects. in the second slide, the presenter used key figures and a unique color for each project to show the connection..

• Xiaoju Chen Defense Slides with Notes

4. Tell a good story 

The committee members do not necessarily have the same background knowledge as you. plus, there could be researchers from other fields and even the general public in the room. you want to make sure all of your audience can understand as much as possible. focus on the big picture rather than technical details; make sure you use simple language to explain your methods and results. your committee has read your dissertation before your defense, but others have not. , dr. cook and dr. velibeyoglu did a good job explaining their research to everyone. the introduction sessions in their presentations are well designed for this purpose. .

• Laren M. Cook Defense Slides with Notes
• Irem Velibeyoglu Defense with Notes

5. Transition, transition, transition

Use transition slides to connect projects , it's a long presentation with different research projects. you want to use some sort of transition to remind your audience what you have been talking about and what is next. you may use a slide that is designed for this purpose throughout your presentation. , below are two examples. these slides were presented after the introduction section. the presenters used the same slides and highlighted the items for project one to indicate that they were moving on to the first project. throughout the presentation, they used these slides and highlighted different sections to indicate how these projects fit into the whole dissertation. .

You can also use some other indications on your slides, but remember not to make your slides too busy.  Below are two examples. In the first example, the presenter used chapter numbers to indicate what he was talking about. In the second example, the presenter used a progress bar with keywords for each chapter as the indicator. 

Use transition sentences to connect slides 

Remember transition sentences are also important; use them to summarize what you have said and tell your audience what they will expect next. if you keep forgetting the transition sentence, write a note on your presentation. you can either write down a full sentence of what you want to say or some keywords., 6. be brief, put details in backup slides , you won't have time to explain all of the details. if your defense presentation is scheduled for 45 minutes, you can only spend around 10 minutes for each project - that's shorter than a normal research conference presentation focus on the big picture and leave details behind. you can put the details in your backup slides, so you might find them useful when your committee (and other members of the audience) ask questions regarding these details., 7. show your presentation to your advisor and colleagues, make sure to ask your advisor(s) for their comments. they might have a different view on what should be emphasized and what should be elaborated. , you also want to practice at least once in front of your colleagues. they can be your lab mates, people who work in your research group, and/or your friends. they do not have to be experts in your field. ask them to give you some feedback - their comments can be extremely helpful to improve your presentation. , below are some other tips and resources to design your defense presentation. .

Defending your doctoral thesis: the PhD viva

Format for defending a doctoral thesis.

Every institution will have specific regulations for the thesis defence. In some countries or institutions, the convention is for thesis defences to be public events where you will give a lecture explaining your research, followed by a discussion with a panel of examiners (opponents). Both your examiners and the audience are able to ask questions.

In other countries, including the UK, the oral examination is usually conducted behind closed doors by at least two examiners, usually with at least one being from another institution (external examiner) and an expert in your topic of research. In the UK the supervisor does not participate in the viva, but may be allowed to observe. Sometimes someone from your own institution is appointed as an independent chair. Although it is now becoming more common for the candidate to have an opportunity to give a public lecture in UK institutions, this does not form part of the examination and may or may not be attended by the examiners.

Viva preparation

Take the preparation for your viva seriously and devote a substantial amount of time to it. The viva preparation checklist may be useful to help you prepare.

Your institution may offer courses on viva preparation and there may be opportunities to organise a practice viva. Take advantage of these opportunities: they can be extremely valuable experiences.

Things you may wish to take with you

• your thesis – mildly annotated if you wish
• a list of questions that you might be asked and your planned responses
• any questions that you want to ask your examiners
• additional notes which you have made during your revision
• list of minor corrections that you have come across during your revision.

During the viva

Your study will have strengths and weaknesses: it is essential that you are prepared to discuss both. You could think of any weaknesses as an opportunity to demonstrate your skill at critical appraisal. Examiners will seek to find and discuss weaknesses in all theses. Do not interpret criticism as indication of a possible negative outcome.

Examiners have different personalities, styles and levels of experience. Sometimes a candidate may feel that a challenge is made in a confrontational way. Experienced, effective examiners will not be inappropriately confrontational, but some will. Do not take offence. A relaxed, thoughtful, and non-confrontational response from you will help re-balance the discussion. Having an independent chair can help maintain a constructive environment.

Useful tips for during your viva:

• Ask for clarification of ambiguous questions or ask for the question to be repeated if necessary
• Take time to think before answering
• Be prepared to ask questions and enter into a dialogue with your examiners
• Be prepared to discuss your research in context of other work done in your field
• Be ready to admit if you don't know the answer to a question
• Be prepared to express opinions of your own

You are not expected to have perfect recall of your thesis and everything that you have read and done. If you get flustered, or need to refer to notes your examiners will understand. They have been in your situation themselves!

After your viva

There are several possible outcomes   of a thesis defence. Most commonly, your examiners will recommend to your institution that you are awarded your degree subject to minor corrections, although in some instances they might ask for more substantial work.

• Complete all courses, exams, and research requirements
• Meet with your advisory committee to ensure that everyone agrees that the work is ready to defend
• Decide on a date for the defense
• Inform your graduate administrator that you have started the process to prepare for your defense

A chair is appointed for each PhD oral defense to monitor and promote fairness and rigor in the conduct of the defense. To help eliminate pre-established judgments on the candidate’s work, the chair should be from a different program/department than the student. For more information about chair responsibilities, read the instructions for the chair .

You must identify a faculty member to serve as chair for your defense. The chair must be:

• A current full-time faculty member at assistant professor rank or higher
• Outside the department offering the degree program, or outside your advisor's department (interdisciplinary degree programs only)
• Someone who has not had prior involvement in your research

The selection of the chair is subject to the approval of the department/program, th Arts, Sciences and Engineering dean of graduate education and postdoctoral affairs, and the University dean of graduate studies.

The chair must be physically present during the entire defense, including the public oral presentation (if applicable) and the questioning session. The chair is welcome to read and comment on the dissertation and/or the defense presentation, but this is not required. The chair does not need to be an expert in your research area.

It is your responsibility to get a copy of the final dissertation to the chair at least one week prior to the defense.

You should begin scheduling the actual defense date three months in advance to ensure that your advisor, committee members, and chair are able to be present and that rooms are available on the date and time selected.  

Defenses can be held on any day the University’s Graduate Studies Office is open (not weekends, evenings, holidays, or the days between Christmas and New Year’s). Check the  academic calendar  for important dates and deadlines.

Use the  PhD calendar  to determine the deadline dates for getting your paperwork to the Office of Graduate Education and Postdoctoral Affairs and department committee.

When all committee members and your chair agree to a specific date and time for the defense, inform your graduate administrator as soon as you possibly can, but no later than six weeks prior to your defense date . Your graduate administrator will advise you of any program-specific requirements for the defense as well as work with you to prepare for your thesis defense. They will also help you determine who will schedule the room for your thesis defense.

You should provide your committee members at least two weeks to read and comment on your dissertation before the date you need to register your dissertation.

Participating Via Video Conferencing

While you, your advisor, and the chair must all be physically present in the room for the defense, other committee members are allowed to participate in the defense remotely via Skype or other video conferencing technology so long as all committee members agree to the arrangement. This must also be approved by the AS&E dean of graduate education and postdoctoral affairs and the University dean of graduate studies before the dissertation is registered for defense.

Someone other than you and your committee must handle the IT setup and be on standby for any problems. If anyone involved finds that remote participation is interfering with the defense, he or she can request that the defense be rescheduled.

We strongly recommend that international students meet with an  International Services Office (ISO)  representative as soon as permission to start writing is granted. The ISO will provide information on visa options, documentation, and timelines for applying for a visa for employment in the United States.

You will register for one of the following categories while preparing your defense:

• 999: Dissertation —Indicates the PhD student has completed all of the requirements for the degree except the dissertation and is in residence as a full-time student
• 995 : Continuation of Enrollment —Indicates the PhD student has completed all of the requirements for the degree except the dissertation and is not in residence as a full-time student

See the registration page for more information about these categories.

The Preparing Your Doctoral Dissertation manual is a great resource to help you bring your dissertation up to the required standard of organization, appearance, and format for the University of Rochester. Before preparing the defense copy of your dissertation, check the contents of the manual carefully to help avoid mistakes that can be time-consuming and costly to correct.

Before beginning your dissertation, you should consult with your advisor for your department or program’s preferred style guide (APA, MLA, Chicago).

Including material produced by other authors in your dissertation can serve a legitimate research purpose, but you want to avoid copyright infringement in the process. For detailed instructions on avoiding copyright infringement, please see ProQuest’s  Copyright Guide .

The University requires that you provide copies of the dissertation to your committee members and exam chair. You should check with your committee members to see if they prefer printed or electronic copies (or both). Printed copies do not need to be printed on heavyweight, expensive paper unless there is the need to do so for figures and images. 

Printing and binding a dissertation can be expensive. You can use the Copy Center or FedEx Office to print and bind your dissertation.

In order to register your dissertation, you or your graduate administrator will need to create a record on the Graduate Studies PhD Completion website . This record will include:

• Degree information
• Past degrees
• Contact information
• The defense version of your dissertation as a PDF
• Other relevant documents

The version of your dissertation attached to your online record is considered the registration copy.

When your PhD completion record is finalized, committee members will receive emails with links to access your record and approve your dissertation to progress to defense. You’ll need to provide copies of the dissertation identical to the registration copy to all members of your committee, including the chair, at least two weeks before the record is finalized. Everyone but the chair is required to comment or sign off on the dissertation before it is submitted.

There may be deadlines for registering your dissertation specific to your program. Consult with your graduate administrator to ascertain those deadlines and follow them carefully.

After all committee members have provided their approval, your thesis will be reviewed by your faculty director/department chair, the AS&E dean of graduate education and postdoctoral affairs, and the office of the University dean of graduate studies. When all of these officials have approved your committee and dissertation for defense, your dissertation is considered registered. You will be able to track these approvals in your online record and will receive a confirmation email when approvals are complete.

The GEPA Office and the AS&E dean of graduate education and postdoctoral affairs, as well as the University Graduate Studies Office, may make corrections to the PDF of your dissertation. This annotated copy of your dissertation, along with the original version, will be stored in the PhD completion website. You are not allow to distribute updated versions of your dissertation prior to the defense, but be sure to incorporate any corrections before uploading your final dissertation to ProQuest®. 

After the defense, if the committee has required major revisions to be approved by one or more of its members, it is your responsibility to provide them with the corrected final version for their approval.  They will be asked to submit written confirmation of that approval to the University Graduate Studies Office. Failure to do so could delay conferral of your degree.

After the defense, you will receive additional instructions by email for completion of all PhD degree requirements.

It is important to walk into the defense knowing that your committee wants you to pass. Even if criticism is harsh, it is meant to be constructive. The defense is not solely an opportunity for the committee to compliment and congratulate you for the work you have done. It is also meant to challenge you and force you to consider tough questions.

The Defense

The best way to prepare for your defense is to regularly attend the defenses of your colleagues throughout your graduate program, not just several weeks prior to your own defense.

You can also talk to people in your department who already defended to find out what their defenses were like. You should also speak with your advisor to get a sense of his/her specific expectations of a defense.

Guidelines for Presentations

Use PowerPoint or Other Software to Create Slides

You should prepare a presentation of the research that comprises the thesis. Your slides should encapsulate the work and focus on its most salient contributions. In preparing, ask yourself these questions: “What do I want people to know about my thesis? What is the most important information that I can present and talk about?”

Here are some basic tips:

• Use text large enough to be read by the audience (especially text from figures)
• Ensure graphics and tables are clear
• Don’t clutter your slides—if necessary, have things come up on mouse clicks
• Use spell check and proofread your slides
• Practice your presentation with your peers
• Work on pronunciation, if required
• Time your presentation to ensure it will fit the allotted time while allowing time for questions

If your defense includes a public lecture, we recommended that you do a trial run a day or two before in the room that has been booked for your lecture. This will allow you to familiarize yourself with the space and the equipment and to address any problems that arise during the trial run. 

Plan your public lecture to allow enough time for questions. Present enough information so that the audience understands what you did, why you did it, what the implications are, and what your suggestions are for future research.

Friends and family are welcome to attend your public lecture. Faculty and students in the audience are given the opportunity to ask questions.

Plan to dress professionally for the defense in the same way you would if presenting a paper at a conference or for a job interview. You will be standing for a long time on the day of your defense. You might want to keep this in mind when selecting the shoes you will wear for your defense.

Essentials for your public lecture include:

• Your presentation
• A laser pointer
• A copy of your dissertation
• A pen or pencil
• A bottle of water 

You will be asked to leave the room while your committee reviews your program of study, and decides whether:

• The thesis is acceptable/not acceptable
• Whether members will ask sequential questions or whether each member will be allotted a specific time period for questioning

The person to start the questioning is designated. You will be called back into the examining room and questioning will begin. After all questions have been addressed, you will be asked to leave the room while your committee decides the outcome of the exam. You will be asked to return to the room to be informed of the outcome by the chair of your exam committee.

• Listen  to the entire question no matter how long it takes the faculty member or student to ask it (take notes if necessary).
• Pause and think  about the question before answering.
• Rephrase  the question.
• Answer  the question to the best of your ability; if you do not know the answer, remain calm and say so in a professional way.
• Remember  that no one will know the ins and outs of the thesis and your research materials as well as you.  You  are the foremost expert in the thesis topic and  YOU know the research involved. Be positive!

Possible outcomes include:

• Acceptable with minor or no revisions (no further approval required)
• Acceptable with major revisions in content or format (in this case, one or more committee members must be responsible for overseeing and approving the major revisions before the final copies are submitted)
• Not acceptable

After the Defense

You can submit the final corrected copies of your dissertation as soon as you address any remaining comments that were brought up during the defense or noted in the registration copy of your dissertation, which will be returned to you usually within a few days before or after the defense. You can take up to one semester following the defense to address any comments, during which you can remain a full-time student. Your degree conferral date will depend on when you submit the final corrected copies of your dissertation.

The day after your defense, you will receive an email from the University dean of graduate studies that provides instructions on how to:

• Submit the final corrected copies of your dissertation through ProQuest
• Provide authorization for the release of your dissertation through UR Research
• Complete a mandatory online exit survey
• Verify to the University dean of graduate studies’ office that the dissertation has been submitted

The University of Rochester requires all doctoral candidates to deposit their dissertations for publication with ProQuest Dissertation Publishing and with the University libraries. Hard copies are not required. The library receives an electronic copy of the dissertation from ProQuest, but students must give the University permission to obtain it.

For questions regarding publishing through ProQuest, contact Author Relations at [email protected] or (800) 521-0600 ext. 77020.

Check with your graduate administrator to see if your department wants a bound copy of your dissertation, and, if so, how the cost of binding is covered.

If you want a bound copy for yourself or your family, you can purchase one through ProQuest .

Autonomous System Testing: Incorporating Physical Environments and Physical Semantics

Abstract : 

As the integration of autonomous systems becomes increasingly common in our everyday lives, their shortcomings and failures become more apparent. Therefore, rigorous validation to ensure their safety and reliability is paramount. Since autonomous systems behavior is predominantly driven by software, and software validation has achieved significant success in validating applications billions of people use today, it seems natural to attempt to apply current software validation to autonomous systems. Such application, however, requires overcoming two key challenges introduced by the differences between traditional software and autonomous systems, namely the physical environment and the systems physical semantics. Without considering these differences, traditional software testing techniques struggle to cope with a large unbounded input space and to effectively target areas of the software that drive the behaviors of the autonomous system. This work introduces techniques grounded in traditional software analysis that overcome these challenges spanning the entire testing pipeline: test generation, test execution, and test adequacy assessment.

In the area of Test Generation, I investigated techniques to produce tests based on a vehicle's kinematics to ensure they aligned with the physical semantics of the autonomous system, all while using parametrizable scoring models to identify tests that stress an autonomous system. Moreover, I leveraged a vast array of existing sensor data from real-world physical environments to identify performance discrepancies across different versions of an autonomous system. The sensor data that yielded discrepancies were then compared against the autonomous systems Operational Design Domain to determine their relevance.

In Test Execution, I have devised a mixed-reality strategy that bridges the gap between simulation and real-world testing. Recognizing that real-world testing, while ideal, is often impractical, hazardous, and expensive, my approach integrates virtual elements into real physical environments. This allows for validating performance and safety while reducing both cost and time. Additionally, I designed a haptic suit for drones, enabling us to test the physical semantics of a drone by applying forces to the drone in the real world.

Regarding Test Coverage, I created Physical Coverage, one of the first coverage metrics for autonomous systems, which considers both the physical environment and physical semantics of the autonomous system. Utilizing physical reachability analysis and geometric vectorization, this metric offers a quantifiable measure of test suite effectiveness. It has proven instrumental in identifying missing scenarios and redundant tests in datasets such as Waymo's Open Perception dataset.

By addressing these challenges across the entire testing pipeline, this dissertation takes a significant step toward creating safer and more reliable autonomous systems.

Ph.D. Student Isabelle Rathbun Receives Department of Defense Fellowship

Isabelle Rathbun , a computer science Ph.D. student at the University of Maryland, has been awarded a National Defense Science and Engineering Graduate (NDSEG) fellowship by the Department of Defense for her research in artificial intelligence within the computer vision and sensor fusion domains. Rathbun was one of 165 individuals from 68 institutions nationwide to receive a three-year NDSEG fellowship this year.

The NDSEG Fellowship program, established by Congress, aims to increase the number of U.S. citizens earning doctoral degrees in science and engineering fields critical to national defense. The program supports students pursuing advanced education in these areas through competitive fellowship opportunities.

The fellowship covers all tuition, mandatory fees, and health insurance, provides a monthly stipend and includes a travel budget for professional development.

“I am honored to have this opportunity as a first-year student,” Rathbun said. “I look forward to taking advantage of NDSEG's resources over the next three years. This support will help me pursue impactful research while building new connections and professional relationships.”

Rathbun's research aims to create more reliable and resilient AI systems, focusing on sensor fusion algorithms central to modern robotics and autonomous navigation systems. By combining complementary sources of information, such as lidar and cameras, sensor fusion allows these systems to perform high-level tasks, like navigation, more effectively than with any single modality alone. However, adding sensors also introduces additional points of failure.

Her research addresses these critical challenges in autonomous systems, aiming to enhance their robustness and reliability.

"Isabelle's research will characterize the performance of sensor fusion algorithms in the presence of failed sensors," said Christopher Metzler , Department of Computer Science assistant professor and Rathbun’s advisor. "She will then develop novel, human-in-the-loop techniques to mitigate the impact of sensor failures. Her research will thus improve the reliability, performance and safety of future autonomous navigation and robotics systems."

In the future, Rathbun plans to continue her research beyond her doctoral studies.

"After I complete my Ph.D., I intend to pursue research in an environment where there is the opportunity for positive impact and pushing the boundaries of cutting-edge research,” Rathbun shared. “I plan to continue developing safer and more reliable technology for public use and deployment, such as in autonomous vehicles and improving their performance in real-world environments with increased uncertainty.”

The NDSEG Fellowship program is critical in workforce development for STEM fields. Since its inception in 1989, the program has awarded nearly 4,700 fellowships from over 70,000 applications.

UB faculty part of partnership to accelerate AI security for Department of Defense

research news

By KEVIN MANNE

Published May 30, 2024

Four UB faculty researchers will serve as key members of a new $1.8 million initiative to secure the U.S. Department of Defense’s most critical artificial intelligence models while also accelerating the technology’s commercialization in the private sector.

Siwei Lyu, SUNY Empire Innovation Professor of computer science and engineering, School of Engineering and Applied Sciences, will serve as principal investigator. And, from the School of Management’s Department of Management Science and Systems, Kyle Hunt, assistant professor, and Sanjukta Smith, chair and associate professor, will serve as co-principal investigators; Dominic Sellitto, clinical assistant professor, will serve as senior personnel on the project.

The four faculty members will work with security for AI firm HiddenLayer as part of an effort by the Air Force Research Laboratory (AFRL) and AFWERX to use AI detection and response to manage critical issues in the Department of Defense. Abigail Maines, BS ’97, MBA ’99, chief revenue officer at HiddenLayer, will serve as main point of contact with the organization.

AFWERX is the innovation arm of the U.S. Air Force and a directorate within the Air Force Research Laboratory that brings cutting-edge American ingenuity from small businesses and startups to address the most pressing challenges of the Air Force. HiddenLayer was awarded the $1.8 million Phase II contract through AFWERX’s Small Business Technology Transfer program.

“This project is part of a critical push toward securing AI models that may be vulnerable to a wide range of attacks,” says Smith. “These models are used in many real-world settings, such as classifying images or identifying fraud, and there is a specific set of attacks that can cause them to misclassify, which can wreak havoc when they are deployed in the wild.”

The Air Force Research Laboratory  is the primary scientific research and development center for the Department of the Air Force. AFRL plays an integral role in leading the discovery, development and integration of affordable warfighting technologies for the U.S. air, space and cyberspace force. With a workforce of more than 12,500 across nine technology areas and 40 other operations across the globe, AFRL provides a diverse portfolio of science and technology ranging from fundamental to advanced research and technology development.

AFWERX employs approximately 325 military, civilian and contractor personnel at six hubs and sites executing an annual $1.4 billion budget. Since 2019, AFWERX has executed 4,697 contracts worth more than $2.6 billion to strengthen the U.S. defense industrial base and drive faster technology transition to operational capability.

HiddenLayer  is the leading provider of security for AI. Its security platform helps enterprises safeguard the machine learning models behind their most important products.

Programming problem patched: Leiden PhD candidate discovers breakthrough in software security

By chance, computer scientist Hans-Dieter Hiep (Leiden Institute of Advanced Computer Science and Centrum Wiskunde & Informatica) discovered a ‘gaping hole’ in a widely used method for evaluating software security. Hiep patched the hole, causing quite a stir in his field. 'It’s not pleasant when a PhD candidate from Leiden comes along and points out that a twenty-year-old proof system is flawed.’ Hiep graduated cum laude on 23 May.

‘Small programming errors can have significant consequences,’ says Hiep. ‘Especially if the error is in the part of the software that handles and protects our working memory.’ These systems ensure, for example, that users can temporarily share their memory without risk. Hiep explains: ‘If there’s a mistake in such an operating system, you can easily get a data breach, and everything is out in the open. Errors in memory security are the leading cause of common vulnerabilities and leaks.’

The threat posed by such bugs to digital security is underscored by a White House press release from last February. It calls on the scientific community to come up with solutions to this ‘persistent problem’.

Eliminating bugs in software

Hiep works on program correctness, which means eliminating bugs in software. ‘This field is already fifty years old,’ he says. ‘I focus on the correctness of so-called pointer programs. These are programs that work with memory addressable by pointers: this includes almost all programs today.’

'As a manufacturer, you must first be able to demonstrate that your printer poses no threat to Microsoft systems.'

For twenty years, there has been a method to prove there are no bugs in such pointer programs: separation logic. It’s a fundamental field with many practical applications. Hiep explains: ‘If you’re a printer manufacturer and you want Microsoft to automatically recognise your printers, you first need to prove that the printer’s software is no threat to their operating system. This is done using separation logic. Facebook also makes extensive use of it. Thousands of programmers are employed there, using AI to continuously analyse for errors in the software. And how does that AI work? With separation logic.’

A gaping hole not everyone wants to hear about

Separation logic is thus a way to find errors in computer programs. But Hiep’s research goes one level higher, as he explains: ‘It focuses on finding errors in that proof system, in the separation logic itself.’ It’s not that the current system is incorrect. ‘That is, if you prove a formula, then it is indeed true. Only I discovered that there are also true formulas that you couldn’t prove with this logic. So you have an incomplete proof system that is correct but cannot prove everything true.’

You could call it a gaping hole in the proof system. And not everyone was happy to hear that. Hiep explains: ‘If you've been working in this research area for a long time, or if your company has invested millions in it, it’s not pleasant when a PhD student from Leiden comes along and says it doesn’t add up. It took quite a bit of effort to get my articles published. But I succeeded.’

‘Suddenly, I was faced with a challenge’

But why investigate something we’ve been (supposedly) successfully using for twenty years? ‘I discovered it almost by accident,’ says Hiep. ‘I initially worked on a new type of separation logic: dynamic separation logic. But then I encountered a problem. I came up with two formulas and wanted to show they were equivalent. They were, but none of the existing systems could prove it: I had found a gap. Suddenly, I was faced with this challenge. It was no easy feat, but I finally managed to close the gap.’

Applying discoveries in practice

Despite being able to start immediately as a university lecturer in Leiden, Hiep chose a new challenge in Cambridge. ‘I’m going to work at Amazon. There, I can immediately apply all my new insights and discoveries in practice.’ And the White House? ‘My dissertation, including an accompanying letter, is already in the mail,’ concludes Hiep.

Hans-Dieter Hiep defended his doctoral thesis titled ' New Foundations for Separation Logic ' on 23 May. He graduated cum laude.

Realisation of the research

Hiep conducted his research at both the Leiden Institute of Advanced Computer Sciences (LIACS) and Centrum Wiskunde & Informatica (CWI), under the daily supervision of  supervisor Frank de Boer and co-supervisors Alfons Laarman and Stijn de Gouw.

Founded in 1946, Centrum Wiskunde & Informatica (CWI) is the national research institute for mathematics and computer science in the Netherlands. It is located at Amsterdam Science Park and is part of the Institutes Organisation of NWO. The institute is internationally renowned. Over 150 researchers conduct pioneering research and share their acquired knowledge with society. Over 30 researchers are also employed as professors at universities. The institute has generated twenty-nine spin-off companies.

PhD Defence Ruth Sloot | Revealing the project and asset management divide - Why infrastructure agencies struggle with IT transformation

Revealing the project and asset management divide - Why infrastructure agencies struggle with IT transformation

Ruth Sloot is a PhD student in the Department of Integrated Project Delivery. Promotors are prof.dr.ir. L. Volker and dr. J.T. Voordijk from the faculty of Engineering Technology.

To effectively support infrastructure agencies in realizing data-driven asset management, we need a better understanding of what this transformation entails and the challenges it brings about. The main objective of this thesis is to explain the challenges faced by infrastructure agencies in their IT transformation journey. Drawing inspiration from the social sciences, this thesis takes a socio-technical perspective to IT transformation, viewing technology as embedded within social structures and practices, and vice versa. The thesis hence considers not only the technical aspects but also the social norms, cultural values and organizational structures that shape an IT transformation journey. Furthermore, it adopts a multi-level approach in studying the challenges at the organizational level and their implications at the infrastructure project level.

The findings provide three key insights. First, the organizational context of infrastructure agencies is constituted by a combination of two conflicting institutional logics: a project organizing logic and an asset management logic. As infrastructure agencies organize most work in projects, the combination of project organizing and asset management created tensions in organizing, performing, learning, and belonging. These tensions may have been unperceived by actors in infrastructure agencies as projects and asset management were segregated into separate organizational units. However, the execution of the IT transformation program made tensions between project organizing and asset management salient, as it aimed to integrate project and asset management information.

Second, three new categories of equivocality – scope, needs, and priorities – persistently hinder the development of organized courses of action and, consequently, of further IT transformation. Equivocality in scope refers to the blurry and debated boundaries of IT development projects, making it challenging for actors to define the scope of the IT and the project clearly. Equivocality in needs involves the diversity among users and their difficulties in articulating and agreeing upon their needs. It highlights the challenges in understanding and addressing the varying requirements and preferences of different stakeholders involved in developing and transforming IT. Equivocality in priorities reflects the difficulty in determining the priorities and interdependencies of activities within the IT transformation program. It underscores the complex relationships between different processes and outcomes, making it challenging for organizations to allocate resources and make strategic decisions effectively. Resolving these equivocalities requires strategies that facilitate collective sensemaking. Failure to make sense of these equivocalities can lead to vicious cycles of ‘stuckness’, confusion, and conflict.

Third, IT transformation requires both a technical and an organizational revolution. The IT tools used for project and asset management are manifestations of the logics embedded in them, and can therefore be sources of path dependency and have lock-in effects. Transforming this landscape of IT tools means transforming project and asset management practices. Through the combination of multiple IT projects within one coordinating IT transformation program, changes can be bundled and coordinated. At the same time, changes are also compounded, resulting in a larger magnitude of changes. Organizations undergoing IT transformation must realize this scale and adjust their strategy accordingly.

These three key insights reveal why infrastructure agencies struggle with IT transformation. By examining these transformation challenges, this thesis not only provides deeper insight into the potential benefits of IT transformation but also highlights the substantial changes that such a transformation entails. The insights gained from these challenges can inform the development of more suitable IT transformation strategies that consider its complexity and scale. This, in turn, can better support infrastructure agencies in transforming from project-based organizations to future data-driven asset managers.

Why Employees Are Your Best Defense Against Cyberattacks: 6 Tips for Fostering a People-Focused Security Posture

H istorically, cybersecurity has been perceived as a technology problem and so, businesses have always passed the cybersecurity responsibility to technology teams. These teams naturally turn to technology tools to solve security problems.

But here's the thing: cybersecurity is not a technology problem; it's a business problem . What's more, most cyberattacks have nothing to do with technology per se. What began as spam has evolved into phishing attacks, and these have grown in sophistication. These scams use social engineering techniques to play on human emotions and trick people into doing things they shouldn't, like clicking a malicious link or revealing personal information.

The Growing Importance of People-Focused Defense

Hackers are ROI-focused. They want to smash and grab whatever they can and move on to the next victim. And so, why spend days, weeks and months analyzing victim environments, searching for vulnerabilities, looking for blind spots in cybersecurity defenses, when adversaries can simply walk through the front door? This is exactly what's currently happening in cyber.

As much as 74% of attacks can be traced to social engineering, stolen credentials and privilege misuse because it's much easier to hack a person and infiltrate an organization rather than breach cybersecurity defenses. This hasn't been the case historically because early computer systems were less immune from internet-based attacks and poorly equipped with native cybersecurity defenses.

Six Tips for Building a People-Focused Security Strategy

In general, we are creatures of habit and can end up being predictable in our thought processes and behavioral patterns; such habits cannot change overnight to prop up security defenses. It needs time and a consistent long-term strategy. Here are six tips that can help boost the people side of security:

1. Focus on behavior: Organizations deliver annual training and believe it's adequate for making employees responsible and cybersecurity aware. Awareness and behavior are not equal: roads have speed limits, but we often break those rules. Focus on training exercises that alter behavior instead. For instance, running bi-weekly phishing simulation exercises can help employees build responsive muscle memory in identifying, blocking, and reporting phishing messages.

2. Position security alongside business strategy: Cybersecurity is often considered a low priority because employees have more important things to do. If leaders change the narrative around cybersecurity, show how it can avoid serious business disruption, boost customer trust and confidence, and increase the bottom line, then chances are that employees will see cybersecurity in a more consequential light.

3. Practice empathy: We each have different levels of skills and security maturity and different attitudes towards cybersecurity. Organizations must acknowledge these differences and practice empathy and patience while coaching employees. Avoid being arrogant, punitive, and fear-focused as this is known to create a toxic environment. On the contrary, create a supportive culture where workers are not afraid to report a breach or social engineering scam or ask questions.

4. Use storytelling to sell your purpose: It's important the employees understand that cybersecurity is a positive — something that helps the business thrive. Use analogies and anecdotes to make your training content more digestible and relatable. Leverage current events and news stories (such as ransomware victims) to educate and advocate security but refrain from using scare tactics.

5. Make it fun and interesting: Cybersecurity doesn't have to be a serious thing. It can be an interesting way to build fun, rapport, and engagement among employees. Use gamification tools and methods, run contests, offer freebies, and recognize people for their efforts and support. Such types of activities can not only motivate people more but can also alter their attitude and mindset toward cybersecurity.

6. Use advocates and influencers: Culture is contagious. Find leaders from within, people who are influential and enjoy a certain level of trust in the company. Leverage their clout to unify the team and influence their security mindset. A positive security culture can accelerate people-focused security outcomes dramatically.

Final Thoughts

While technology-based security controls are important and should be deployed, solely relying on them may not always be sufficient to prevent security breaches. Therefore, people-focused security measures have become crucial. By providing thorough training to employees, organizations can instill a strong commitment to security in their workforce.

Cultivating security intuition among employees acts as an additional layer of defense, compensating for potential shortcomings in technology-based controls. With well-trained employees who prioritize security, organizations can strengthen their overall security posture.
