About
Hi, I'm Jun Seo Lee (이준서). I'm studying Commerce with a minor in Data Science at the University of Virginia's McIntire School of Commerce (Class of 2027), concentrating in IT on the Analytics and AI track. I transferred to the University of Virginia from Yonsei University in 2022.
I like turning messy information into clear, data-driven decisions. I'm currently a research assistant at the Korea Defense Veterans Association. This summer I was a product manager intern at Quotain in New York, where I shipped an automated cold email outreach system and ran the A/B test that the team adopted. Before that I led a team of research interns at the Global ESG Foundation and did market analysis for a state-owned insurer in Jakarta while interning at House of Analytics. In between, I served 18 months as a KATUSA infantryman with the U.S. Army in Korea, where I led a four-person team and interpreted for joint ROK–U.S. operations.
I'm interested in product, analytics, and consulting. Outside of work you'll find me running 5Ks, playing soccer, hiking, camping, shooting pool, or playing Tetris.
