USING MICROBIOLOGY TO IMPROVE HUMAN HEALTH
Looking back, how did your path unfold from TGS to where you are today?
When I joined TGS, I wanted to be a travel journalist. I envisioned trekking through far-off lands, meeting people with lives very different to my own, and sharing their stories with the world. TGS felt like the perfect place to pursue that dream.
However, as I learned more about the people and places we visited—from seeing first-hand how the after-effects of the atomic bomb changed lives in Hiroshima, Japan, to designing VR public health interventions in Melbourne, Australia—I realized that science could empower me to do more than just observe and describe. It could help me imagine interventions and discover new knowledge with the potential to improve people’s daily lives.
When I graduated from TGS, I started my undergraduate studies at Reed College, a small liberal arts school on the west coast of the USA. Reed was a fantastic place to land after TGS; I co-authored a scientific paper about bacterial metal metabolism, earned my nuclear reactor operators license, and graduated in 2024 with my degree in biochemistry and molecular biology.
After graduating, I moved with my amazing partner Soeun Kim (Class of 2020) to the other side of the country, and for the past two years I’ve been working full-time in microbiology labs at Brown University and Harvard Medical School. In the Fall of 2026, I will continue my quest to understand the lives of the trillions of bacteria that call our bodies home as I pursue my PhD in Biology at MIT.
When you reflect on your time at TGS, what has stayed with you the most, and how has it influenced the way you approach your work today?
When you visit the doctor with a bacterial infection, they may take a sample of your blood to learn more about the infection and what’s causing it. This process takes several days— the handful of bacterial cells present in the blood draw need to be left overnight to multiply into billions of cells that can be tested in clinical labs.
As a research assistant at Harvard Medical School, I work towards rapid infectious disease diagnostics, growing bacteria in tiny microfluidic devices and imaging them using microscopes. By extracting as much information as possible from this initial handful of bacterial cells, my research aims to drastically shorten the time between infection and effective treatment. I love this work because I can contribute to technology that could save lives, while learning more about the unseen world of microorganisms.
When you reflect on your time at TGS, what has stayed with you the most, and how has it influenced the way you approach your work today?
When I joined TGS in 2017, the transition to a project-based learning curriculum was in full swing. We learned along with staff and educators what it meant to be educated by the world around us, outside of the bounds of the traditional classroom. In practice this often meant learning how to fail upwards, expect the unexpected, and even occasionally making things up as we went along. Most importantly, we learned to ask and answer questions where the end of the story wasn’t written yet.
As a scientific researcher, my job is to push past the boundaries of existing knowledge, trying things no one has done before and drawing meaningful conclusions from the process of experimentation. The boldness, initiative, and grit instilled by a TGS education have become some of my most useful tools for chipping away at the unknown and persevering in the face of uncertainty.
What piece of advice would you share with students and parents who are considering TGS?
A TGS education is an improbable, spectacular, surprising, and at times indescribable experience. Riding camels across the Sharqiya sands of Oman, or learning to surf in a Costa Rican beach town, it was hard to picture what my life after graduation might look like. If you’re considering a TGS education, here’s my advice: don’t worry too much about what happens afterwards, because TGS will turn you into exactly the type of person who will make the most of whatever challenges and opportunities come your way.
