I build learning systems that generalize across domains: foundation models, reinforcement learning, and speech and language decoding, running where the stakes are real.
Currently a professor of AI, psychiatry, and neuroscience at Mount Sinai, and a Senior Computer Scientist with the US Department of Veterans Affairs. Previously Google X / Brain / DeepMind, IBM Research, Amazon, and Microsoft Research.
