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.

On April 14, 2025, Blue Origin launched its 11th human spaceflight, NS-31, marking the first all-women commercial spaceflight crew. Aboard the New Shepard capsule were Aisha Bowe, Amanda Nguyen, Gayle King, Katy Perry, Kerianne Flynn, and Lauren Sanchez. While the flight made headlines as a symbolic milestone, it also marked a change in how we think about access to space and accountability in a warming world.

In 2021, I worked alongside the U.S. Space Force at the Air Force Research Laboratory during the year Virgin Galactic launched its first fully crewed spaceflight. A few days after the flight, I visited Spaceport America to see the launch site in person, an early glimpse into the operational reality of commercial space. When Blue Origin’s NS-31 mission made headlines this year, I was genuinely excited. It brought back the sense of possibility I felt standing at Spaceport America years earlier. Commercial spaceflight had taken another step forward, and I wanted to understand what that meant. What does this flight reveal about the technical maturity of suborbital travel? And how might it shape the future of spaceflight design, regulation, and environmental impact? In this article of Now & Next, I take a closer look at what NS-31 tells us about the state of commercial space, and where it’s headed.

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.

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.

His research focuses on international political economy, particularly in the realm of international institutions, and serves on the editorial board of International Organization. His publications span various scholarly journals, such as American Political Science Review, International Organization, and Journal of Politics, showcasing his extensive contributions to academia.

As a former student in POL 396: International Organizations, I was introduced to a wide range of research on international organizations, including works by academic scholars and Professor Vreeland himself. While continuing my Research Insights Series from last spring, a series of blog posts to provide glimpses into the current research landscape at Princeton, I knew I wanted to interview Professor Vreeland. As my first politics course at Princeton, it sparked my curiosity about political science research, and more broadly, research in the social sciences.

Seasonal Series: An Interview with Eric Ahn

Posted on April 19, 2024May 9, 2024 by Shannon Yeow

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.

Research Insights Series: An Interview with Michael J. Thate

Posted on April 10, 2024April 8, 2024 by Shannon Yeow

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.

My Second Year BSE Fall Experience in the Engineering Sequence and Reflection

Posted on December 15, 2023December 12, 2023 by Shannon Yeow

After attending my final class of the semester, the feeling that I was done with my BSE requirements finally settled in. From now on, as a COS BSE major, I would have much more flexibility in my class options with my prerequisites complete. Having written both My BSE Fall Semester Experience in the Engineering Sequence and My BSE Spring Semester Experience in the Engineering Sequence (which I recommend you read first before reading this), I wanted to write a final article to reflect on my experience now that I’ve officially completed the Engineering Sequence. To reiterate one last time, the Engineering Sequence is a set of five courses intended to fulfill the engineering degree requirements through an introduction to engineering fundamentals in the context of real-world applications. BSE degree requirements include four semesters of math, two semesters of physics, one semester of chemistry, and every first-year student is required to take one semester of writing seminar and fulfill various distribution requirements for general degree requirements. This semester, I took the final course in the Engineering Sequence, Multivariable Calculus, which means that along with taking chemistry, I have completed my BSE degree requirements.
