Jake Snell is a DataX postdoctoral researcher in the Department of Computer Science at Princeton University, where he develops novel deep learning algorithms by drawing insights from probabilistic models. He is currently serving as a lecturer for SML 310: Research Projects in Data Science.

As I dive deeper into my computer science coursework, I’ve found myself engaging increasingly with statistics and machine learning (hereafter abbreviated as SML). Opportunities to conduct SML research are abound at Princeton: senior theses, junior independent work, research-based courses such as SML 310: Research Projects in Data Science, joining research labs, and much more. There is such a wide variety of research opportunities, and so many nuanced pathways that students can take while exploring SML research. So, for this seasonal series, I wanted to speak with professors and researchers who are more advanced in their research journeys to share their insight and advice to undergraduate students.

Eric Ahn Headshot
Eric Ahn ’24, from Suwanee, Georgia, is an Operations Research and Financial Engineering (ORFE) major at Princeton University. Ahn is the Class of 2024 Treasurer, as well as a member of Manna Christian Fellowship and Kindred Spirit. This coming summer, Ahn will work as a Trading Intern at IMC Trading before returning to Princeton in the fall to obtain a graduate degree in finance.

In the spirit of upcoming senior thesis deadlines, I wanted to interview a senior currently working on their thesis. As an underclassman that doesn’t have to worry about any form of independent work yet and a COS BSE major, one of the only majors exempt from the senior thesis requirement, I’ve always been curious about the thesis writing process and what a BSE senior thesis entails. As a part of our Seasonal Series, I am excited to present my interview with Eric, as he shares his ORFE senior thesis, his interest in finance, and his advice for rising seniors.

Reading for Fun: How and Why

Often when I mention the subject of reading for pleasure’s sake in conversations with other Princeton students, I hear the same story repeated with a twinge of sadness and a sense of resignation to the seemingly-inevitable. Most of us seem to have begun our respective childhoods as avid readers who could barely be seen apart from a book. We enjoyed all sorts of reading, and it was not a tiring task but an exciting opportunity. Over the course of many grueling years of schooling filled with assigned readings and the like, this voracious appetite for literature seems to have been largely snuffed out. If you, like me and many others, have drifted away from the pleasurable pastime of reading for fun and wish that you could regain a bit of that excitement which marked your early years, this article will give a few suggestions for how and why you might go about effecting this turnaround.

Research Insights Series: An Interview with Michael J. Thate

Michael Thate Headshot
Michael J. Thate is a Research Scholar for Responsible Tech, Innovation, and Policy at Princeton University’s Faith & Work Initiative, and Lecturer at the Keller Center for Innovation in Engineering Education and the School of Engineering and Applied Science, with a background in law, design, ethical philosophy and religious studies, and GIS. Michael’s academic interests and focus are informed and complemented by his corporate experience where he advises across STEM industry sectors on matters of brand equity, communication strategy, institutional trust, ethics, and regulatory strategy.

I had come to grapple with the idea of ethics in the engineering world when I became fascinated with Department of Defense (DoD)-related technologies and applying my computer science background to space-related development. I was struggling with the ethics in relation to human ecology, especially in defense and technology militarization, and how to balance this struggle with my fascination for the technologies present in the industry. Michael and I first connected via email over aligned interests in professional codes of conduct in defense and security AI systems. 

As I began this research insights series, I sought to interview Michael in order to get a sense of what his research might look like from a highly interdisciplinary perspective, and how ethics, something that is prevalent in any academic area, is present as a core focus of research. In this article, I’m excited to present my interview with Michael, focusing on human interactions with the natural world, and how to quantify “life” and its “value” within a vast ecological space.

Please note that one response discusses animal injury and death.

Research Courses at Princeton

The structure of a “standard” Princeton course usually includes a mix of lectures, precepts, or seminars which likely have a midterm and final. While some of these courses may have “lab” components where you spend a couple hours once a week doing a hands-on assignment, there exist many courses at Princeton which are instead entirely focused on conducting hands-on, lab-based research with a small team that works closely with professors who provide mentorship as you work on an original research project. If you’ve ever wanted to take a class that is far different from anything else at Princeton by teaching you hands-on skills and giving the opportunity for a new project, these types of courses might be for you!

Some of these courses are year-long sequences like AST250 Space Physics Lab I and AST251 Space Physics Lab II, which I took during the 2022-2023 academic year. This was one of my favorite course experiences at Princeton and was certainly the most engaging. The skills we learned were invaluable, and as we worked closely with the professors and each other, our year-long project became an unforgettable experience.

Research Communication and Community: Reflecting on the Princeton Correspondents for Undergraduate Research

Melissa Parnagian; Stacey Huang; Alec Getraer

Each month in the Office of Undergraduate Research newsletter, we highlight recent posts by Princeton Correspondents on Undergraduate Research (PCUR) authors. This month, we are looking back on ten years of PCUR as we celebrate the tenth anniversary of OUR.

PCUR began the same year as OUR – with the first posts published in September 2014. We invited PCUR alums to share their perspective on their time as a correspondent, including two who were part of the very first PCUR cohort. Read on to learn about how PCUR serves individual correspondents and the larger Princeton community alike, and if this all sounds like something you’d like to be a part of, Princeton first-years through juniors are encouraged to apply here to join PCUR next fall.

Tips for Recruiting Interviewees: My Qualitative Research on ChatGPT Use in CS Education

Last semester, I interviewed Albert Lee ‘24 to get a glimpse of what conducting qualitative research for sociology Junior Papers can look like at Princeton. (If you’re interested in reading that piece, click here!). Discussing qualitative research with Albert was exciting because his words of advice were quite applicable to the qualitative Computer Science research I was conducting in COS 436: Human-Computer Interaction (HCI).

Prior to taking COS 436, I had little idea of what qualitative research looked like in Computer Science, particularly because many of the CS courses I had taken were quantitative, involving systems, mathematical models, or theory. Taking the course opened my eyes to a whole side of research: interview-based qualitative research. For my semester-long research project, my team and I aimed to dive deeper into educators’ opinions on the use of ChatGPT in CS education.

Enhance your Research with Princeton’s Coin Collection

Students at Princeton are fortunate to have access to one of the largest collections of coins anywhere in the United States. Made up of roughly 115,000 items, the collection includes coins, paper money, medals, and other tokens covering almost the entire history of human money— in fact, the university has coins minted in the 6th century BC by Croesus, who is credited with inventing the first system of gold and silver currency. The university’s collection serves many purposes. For example, you may have been in a class which has gone down to Firestone C Floor to look at coins from the time and place you were studying. The coins are also used for exhibitions and workshops. I’m writing here to explain to you how you can use these coins to do great research.
