Data is everywhere. Whether it’s to track your music listening habits, analyze stock market trends, or understand scientific research, data is most valuable when it can be easily interpreted. This is where data visualization comes in: to transform raw data into clear, engaging visuals.

The Princeton University Library has a wealth of resources and research guides, including guides tailored specifically to data visualization in programming language R and statistical software Stata (often used in economics courses). However, not as many PUL research guides are currently available on data visualization in Python. If you haven’t heard of Python before, it’s a popular programming language that can tackle a versatile range of applications, including data analysis and artificial intelligence. While Stata and R are both excellent choices for statistical analysis and visualization, Python stands out for its flexibility, interactivity, and seamless integration with web development and machine learning applications.

In this article, I wanted to present a commonly-used Python library for data visualization: Matplotlib. By learning how to use Matplotlib, you’ll be able to take your data and turn it into visuals that communicate your findings effectively—a key skill whether you are analyzing survey results, studying statistics, or working on research projects!

The end of the semester is often accompanied by deadlines for semester-long projects and final papers (including the infamous Dean’s Date deadline, which past correspondent Ryan Champeau has amazing advice on!). For some classes, students may be asked to create an academic or research poster and present their work to their peers in a poster session. A couple of courses I have taken where I produced a final research paper were COS 484: Natural Language Processing and ASA 238: Asian-American Psyches.

In ASA 238, the department provided funding so that all students in the class could have their poster printed through Princeton Print & Mail Services. However, this option typically is not free-of-charge to students. Moreover, since this process typically takes 4-5 business days after the proof is approved to be printed, course instructors may set conservatively early deadlines so that all students’ posters may be printed on time. With more deadlines in other classes, this can create additional stress.

The great news is, this stress can be avoided with a free, straightforward alternative: utilizing the Makerspace’s Large Format Printer. The Princeton University Library (PUL) Makerspace is a creative space on the A-level of the Lewis Science Library open to current students, faculty, and staff. If you’ve never used the space before, it might be daunting, but I hope this article will clarify the process and assuage any fears you may have!

Harmonizing Research and A Cappella: How Music Fuels My Scientific Journey

Imagine standing in front of a big audience, heart racing, ready to blend your voice with others and hit the notes of an intricate a cappella arrangement. Every beat, every breath, is crucial. Every time I stand on stage or under an arch with my a cappella group, the Princeton Footnotes, I think of how similar singing and music feels to what I do in the lab. You might be thinking that singing in an a cappella group and doing research are worlds apart. However, these two passions have formed a bond in ways that I never believed possible. In fact, the creativity, collaboration, and discipline I have channeled in being a part of the Footnotes have made me a better researcher—and vice versa.

Reflection on my personal experience tackling a new research paradigm

I’ve always believed in challenging myself to learn new methodologies and explore new fields in my research. Yet, there’s a fine balance between tackling a new challenge and feeling over your head. Reflecting on my past summer conducting a project in a completely new research paradigm, I wanted to take a moment to share my experience in the hopes of encouraging other students to be unafraid to undertake novel endeavors.

I had the life-changing opportunity to research the dose-response of the oral antiviral ensitrelvir for treating mild to moderate symptoms of SARS-CoV-2 with the Schiffer Lab starting this past June as an intern in the Fred Hutchinson Cancer Center Infectious Disease Sciences Internship Program. This project employed a very different application of my interests in healthcare and computer programming than I’d ever done before. Wide-eyed with amazement and curiosity, I delved into the fields of pharmacology, clinical trials, mathematical modeling, infectious diseases, and computational simulations. I remember learning about my project goals for the first time and thinking: “Wow, there are thousands of other students who would make a much better intern on this project”. This overwhelming imposter syndrome is something that I’ve often struggled with during my past research experiences when walking into new fields for the first time. But, thanks to the incredible mentorship of the Schiffer Lab and the tips that they shared with me, I overcame this fear and was able to grow into a more interdisciplinary and confident researcher this summer. I hope to pass on this same inspiration to other students here.

Mentorship Matters: A Summer of Research and Growth

When I first walked into the lab this summer, I thought research was all about running experiments and gathering data. What I didn’t expect was how much the people around me—the mentorship and the shared triumphs and failures—would shape so much of my learning and how I view scientific research.

Starting a research position at a bioengineering lab over the summer was really intimidating for me, especially as an undergraduate. At the start, I felt like the most inexperienced person in a room full of graduate students, postdocs, and faculty who seem to have it all figured out. Although I’ve learned or at least seen a lot of the quantitative and qualitative components in my Chemical and Biological Engineering course, I did not have much hands-on experience and critical thinking that comes with actually doing experiments. That’s when I realized how big of a role a mentor plays.

As we step into the new school year, woman-identifying undergraduate students across campus are looking to take their first steps into research. This process can be new, daunting, and sometimes, downright terrifying. It’s scary to step into a room where you are the first, the only, or both. That’s why it’s imperative to support women-identifying students in empowering research communities, advocating for their learning goals, and asserting themselves in new research settings. For allies, there are also important ideas shared by woman-identifying researchers about the best ways to support their success.

Effortless Perfection at Princeton: The “Perfect” Thesis is Really Hard Work

My final senior thesis!

I’ve always loved reading through senior thesis titles and thinking “Wow, that’s clever,” “That’s genius,” “I wonder how they came up with that.” The senior thesis, which many seniors refer to as a full-blown novel, is supposed to be a senior’s finest work and proudest possession. It looks impressive in its black book with gold font. It is 115 pages. It has fancy acknowledgments. As a first-year/sophomore, and even as a high schooler on tour, I was in awe at how seniors could create such a perfect paper. It isn’t until now that I know the answer: hard work.

My Experience at the 13th U.S. National Combustion Meeting

Posted on April 7, 2023April 6, 2023 by Agnes Robang

From March 19 to 22, 2023, I was at the 13^th U.S. National Combustion Meeting presenting a research poster. My work was titled, “Deep Learning Modeling of the Filtered Generalized Progress Variable Dissipation Rate in Turbulent Premixed Combustion”. In my junior year, as I was planning what to work on for my thesis and what goals I hoped to attain, I determined that I wanted to go the extra mile in my research, enough to be able to go to an academic conference. With some hard work, the patient guidance of my adviser Prof. Michael Mueller, the support from my labmates at the Computational Turbulent Reacting Flow Lab, and the funding from several sources (MAE, CST, OUR, and ACEE), I was able to attend this conference! This was my first research conference, and I cannot overstate how valuable this experience has been to my growth as a researcher.
