About

I am currently in medical school at Yale, where I am now on a research year and will graduate in 2027. I work on health outcomes research (with Harlan Krumholz) amongst other things.

I like thinking about clinical trials, biotech companies, and medical research. I write about these things on Substack and X. I also host the Behind the Science podcast for the Journal of the American College of Cardiology.

If you are working on or thinking about something interesting in medicine or biology, feel free to reach out.

Previously, I worked at Delfi Diagnostics as a data scientist. From 2018 to 2021, I was an undergraduate at Johns Hopkins where I majored in applied math and worked on using cell-free DNA to detect cancer early detection in the Velculescu Lab. I spent my summers at IBM Research working to develop new ensemble learning algorithms.

Other things I enjoy include playing soccer, trying new cocktail bars, spending time with friends, cooking, and reading.
