About Me

I’m a healthcare data scientist and a Research Assistant at Cedars‑Sinai Medical Center in Los Angeles, where I build clinical AI and machine‑learning systems, from LLM‑based phenotyping agents to multimodal deep learning on breast MRI for predicting treatment response.

I earned my B.A. in Biology from the University of Chicago in 2023 and my M.S. in Biostatistics from Columbia University Mailman School of Public Health in 2026, where I worked with Professors Linda Valeri and Todd Ogden on causal mediation analysis, functional data analysis, and other methods that bridge statistics and public‑health applications. I’ve also analyzed Phase 3 clinical trial data with Bristol Myers Squibb and IQVIA.

My broader interests span clinical AI, causal inference, survival analysis, functional data analysis, animal morphometrics, and ecological and environmental systems.
