In Defense of Core Lab

Many STEM majors here have the same rite of passage: core lab. For non-lab majors, core lab is a class that is purely to teach you about lab techniques and critical thinking skills that are useful for writing our theses. They usually involve a bit of a simulated lab experience where you discover new findings while the teachers guide you through the motions of a lab research experience.

Molecular biology’s core lab meets twice a week for 3 hours and then a small 50 minute lecture/precept on Fridays for half the semester. Other majors have similar constraints. However, while at first it may seem a bit overwhelming and even redundant if you’ve already done these procedures in a lab or are in a lab that definitely will not be using any procedures you learn, core lab goes beyond just teaching you technical skills.

I too was confused as to why I was here and why this mattered, but over time, I began to internalize one of the real skills this class is meant to teach you, something that pipetting will never give you: asking the right questions.

Facilitating a Research Discussion in COS 436

Having facilitated a precept discussion in COS 436: Human-Computer Interaction, I was able to reflect on what it means not just to thoroughly read a research paper, but also to guide my peers through a structured discussion based on common threads reflecting their thoughts and insights. COS 436 explores how technology and design shape human behavior and counts towards computer science degree progress as a fulfillment of the breadth category. Engagement with foundational research papers in the field and a semester-long research project are the core components of the course. Each week, students are responsible for writing discussion posts on assigned research papers and take turns facilitating precept discussions.

Jumping Back In!

The summer is always a great time to get involved in research, whether on campus or off campus. One common challenge, however, is figuring out how to actually become a part of those research opportunities. At the end of this summer, I was fortunate enough to be able to return to the research team I worked with last year. While it was exciting to once again be working on the study (an investigation into the effectiveness of peer coaching on high blood pressure) it was a different experience the second time around. Jumping back into any project can introduce new challenges, and research is no different.

The Art of Bouncing Back

Spring is a bit of a bittersweet time for me every year. When the sun comes out, so does any brain cell willing to do work. Summer is right around the corner, and things just seem to drag–even in the quick Princeton semesters. However, that ‘summer right around the corner’ thought is not always an exciting one. With summer comes the prospect of internships, and perhaps more pressing: the lack of thereof. In a previous post, I discussed tips for applying to internships, but by now, you may have already heard back. If you have heard back and the email made your heart sink to your stomach, this post is for you. I’m here to remind you that internship rejections are not the end of the world.

Encounters with Mentorship

As I was graduating high school, everyone – whether it was friends, teachers, or family – told me I had to find a good mentor. I didn’t really know what this meant in the context of college. I had experienced instructive relationships with coaches and teachers before, but I didn’t really know how that would translate into a research-driven environment.

Now as a sophomore, I understand that especially before declaring a major, it can be challenging to forge mentorship connections. Still, during the first two years of my undergraduate experience, I have encountered mentorship in a variety of ways that I would have never expected. Whether it was through my lab-based courses, an internship, or even a recent serendipitous moment, quality mentorship has been a defining part of my Princeton experience.

Thanking Your Mentors: Tips on Writing Your Research Paper Acknowledgements

When I sat down to write the acknowledgements for my senior thesis, I realized something surprising: my department’s resources on how to write a thesis or independent work paper didn’t include any advice on writing this section. In some ways, that makes sense. Most readers focus on sections like the abstract, methodology, and results, which really serve as and highlight the key contributions of the paper. But having guidance on how to write acknowledgements can go a long way in helping students thank the people who made their research possible. In this article, I’ll share a few tips for writing acknowledgements—whether you’re submitting a STEM paper to a conference or wrapping up your senior thesis.

Paying it Forward: A Faculty Perspective on Mentorship in Research

Posted on April 18, 2025April 15, 2025 by Shannon Yeow

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.

The Importance of Humanities and Social Science Classes: In which a STEM major reflects

A lot of my previous posts are mostly concentrated on research and science, and that’s because those are the things I love. However, taking a psychology class this semester that had a more social sciences approach made me think about my story in STEM. In particular, a part of the lecture that stuck with me was the “stereotype threat”. The stereotype threat is the fear of proving a stereotype right. I’m not good at math, and I’ve always thought that would just be the way life goes, but last year, I took MAT103, and I did quite well (it’s one of the easier math classes of course, but the bar is low for me). In fact, it was my easiest class. This really changed my perspective on my math skills. When I reflected on my experience with math, I realized that this mindset I have about it was cultivated by my gender.

Now & Next: Illuminating Solar Innovations with Barry Rand

Posted on April 11, 2025April 3, 2025 by Shannon Yeow

Professor Barry Rand stands at the frontier of sustainable electronics and energy solutions as a Professor of Electrical and Computer Engineering and the Andlinger Center for Energy and the Environment at Princeton University. His work in thin-film electronics and photovoltaic materials offers promising paths toward greener technologies, with real potential to reshape how we power our world.

As a student in his ENE 431: Solar Energy Conversion course, I’ve had the privilege of learning from Professor Rand this semester. This course has challenged how I think about energy and prompted me to look more closely at the systems that power the world. What stood out to me wasn’t just the technology, but the sense of possibility it held. I found myself thinking more seriously about what the future of energy could look like, and who’s shaping it. That curiosity led me to interview Professor Rand for Now & Next, where we discuss his research in thin-film electronics and where he sees the field heading.

Heads Up: You Might Need Study Approval from the Institutional Review Board

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.
