Hello! I'm a software engineer at Epic on the Curiosity team building foundation models on EHR data to predict medical outcomes. I did my undergrad in CS and math at UMass Amherst, along with a combined masters in CS as a Bay State Fellow. I was advised throughout by Professor Jeff M. Phillips of University of Utah. I'm broadly interested in understanding what modern ML models learn and why they generalize. I've worked on LLM interpretability, robust statistics, and the evaluation of language models.
