I'm a member of technical staff at Anthropic, working to ensure the world safely makes the transition through transformative AI.1 I'm currently doing pretraining science. Before that I was on the Frontier Red Team,2 where I co-started our cyber evaluations effort and helped with bio and cyber evaluations for Claude 3.3

Earlier, I worked on AI control4 and interpretability5 at Redwood Research, did reinforcement learning research with George Konidaris while getting a BS/MS at Brown, and interned at Jane Street.

Outside of work, I like ultimate frisbee, biking, and playing the flute.

I'm hiring.
