I'm lead ML engineer at a stealth startup building a novel RF drone localization system deployed in Ukraine. Previously worked on causal inference and ML at QuantCo, and interned at Citadel.

I studied applied math at Harvard, graduating with highest honors. My thesis was advised by Scott Kominers and Morgane Austern.

Interested in ML, markets, and defense. Find my work and reading list here.
