I am a first-year computer science PhD student at NYU Courant and CILVR group, advised by Sumit Chopra and Rajesh Ranganath. I am broadly interested in core machine learning and its application in healthcare. I have previously worked on diffusion models, reinforcement learning, and interpretability.

I obtained my BS in Computer Science with a double minor in Mathematics and Economics at Duke University, where I received Graduation with Highest Distinction and Alex Vasilos Memorial Award. I was very fortunate to work with Cynthia Rudin, Brandon Fain, and Anru Zhang. Before transitioning to machine learning, I was an economics student interested in finance, an accordionist, and a marathon runner.

My hobbies include playing Bayan accordion, running, and road trip.
