David Walker is a Professor of Computer Science at Princeton University whose research focuses on programming languages, formal methods, and computer systems. Known for his commitment to advancing both theoretical and practical understanding in the field, Professor Walker also plays a central role in mentoring students.
As someone who completed my junior independent work under Professor Walker’s guidance last semester, I’ve had the chance to witness his thoughtful mentorship firsthand. In a research culture where both the technical challenge and emotional uncertainty can feel overwhelming, I’ve come to appreciate how crucial the human side of research is—how we learn from and grow with those who guide us. With that in mind, I sat down with Professor Walker to explore how he thinks about mentorship: what it looks like, why it matters, and how he helps students, like me, find their footing in the world of research.

Independent research at Princeton offers an incredible opportunity for students to explore their academic interests and gain experience in the research world. This year, I’m working on my Senior Thesis with Professor Aleksandra Korolova, conducting an audit of Google ad delivery optimization algorithms. Specifically, I am studying whether aspects of advertisements—the image, text, links, and so on—impact the demographics of the audience to whom the advertisement is delivered.
In the fall, many people were curious about how my thesis was progressing. The truth was, for a few weeks, I hadn’t started running any experiments, since I first needed my research to be approved by the Institutional Review Board (IRB). Through this experience, I both gained insight into the IRB process and found that many students had never even heard of the IRB. In this article, I share my experience and offer advice for students who are planning to conduct independent research.
Hailing from Saipan and South Korea, Cevina Hwang is a junior in the Ecology & Evolutionary Biology department. With a longstanding interest in the field of dentistry, she chose to expand upon this passion through her junior work, where she will be exploring the evolution of the human jaw and teeth.

If I have to be completely honest, dealing with citations is my least favorite portion of the academic writing process. Ascertaining what citation style I need to use, successfully figuring out how to actually format citations in that style, and managing the hodgepodge of footnotes and endnotes are all tasks that seem, to me, cumbersome. Of course, these are necessary tasks: it is imperative that if we paraphrase, quote, or utilize in any way the work of others, we should always attribute the proper credit to them. But recognizing the importance of academic integrity doesn’t prevent us from still finding the task of dealing with citations to be a chore! If you’re in the same boat as I am, I’ll try to provide some advice and tips on dealing with citations!
Anna Calveri ’26 is a junior in the Computer Science department. On campus, she is a member of Princeton University Robotics Club, Sympoh Urban Arts Crew, and Colonial Club.
The senior thesis is a hallmark of the Princeton experience, giving students the opportunity to conduct original research under the mentorship of a faculty adviser. Every senior is required to write a thesis, with the exception of Computer Science majors in the Bachelor of Science in Engineering (B.S.E.) degree program. Instead, these students are required to undertake a substantial independent project, called independent work (IW), which can take the form of a traditional one-on-one project with an adviser, an IW seminar where a small group of students independently conduct projects tied to the seminar’s main theme, or an optional senior thesis.
In 2022, I interviewed Shannon Heh ’23 about her experience in an IW seminar, where she highlighted the structure and guidance the professor and course seminar. This year, I wanted to explore the perspective of a B.S.E. Computer Science student who pursued a different option: the one-on-one IW project.
Anna Calveri ’26 stood out as the perfect person to speak with, not just because of her exciting research at the Princeton Vision & Learning Lab led by Professor Jia Deng, but also because she began her project during the summer as a ReMatch+ intern and built on it during the fall semester. While many students only work on their IW within a single semester, Anna’s approach of extending her research across both the summer and fall gave her the chance to deepen her research and hit the ground running with impressive progress.
You’ve finished a research project and now you’re on to the final step: presenting your work! It’s time to share the incredible work you’ve done with the general public, and one of the best ways to do so is to create a poster conveying the significance and conclusions of your research. This will be an essential skill during your time at Princeton whether for a course or as a part of your junior and senior independent work. If this is your first time creating a poster presentation, check this blog out!

You’ve brainstormed a great idea for your research project. You have the details of your topic all figured out, but you need some assistance with figuring out the logistics of the financial aspects that come with your great idea.
If that’s you, here’s a quick guide on one way of securing funding as a Princeton student!
The Princeton Index of Medieval Art used to be a physical register, much like this one.
Many academic disciplines engage with visual art, whether from the standpoint of art history, material culture, or even paleography. The Princeton Index of Medieval Art is a unique database well-suited to the needs of researchers across various fields. Whether history, comparative literature, art, or classics, the index gathers a vast amount of information on Late Antique and Medieval Artworks, neatly sorted in an accessible way.
Whether writing a paper or providing a presentation, you will often find yourself relying on the completed work of others to synthesize information about a subject. An essential part of using these outside sources is to give their owners rightful credit in your references! Read some tips below on making citations easier.
Citations can be the most dreaded section of your writing. Finish your references with ease using this guide!
