I am an American AI researcher.
I currently work at Meta Superintelligence Labs.
From 2023 to 2025, I was at OpenAI, where I co-created o1 and deep research.
Before that, I was a research scientist at Google Brain. My work helped popularize chain-of-thought, instruction tuning, and emergent phenomena.
An invited lecture I gave at Stanford with my colleague Hyung Won Chung is available on Youtube.
