Sergio Charles

I’m a co-founder of Thesis Labs, accelerating AI for scientific discovery. Previously, I was an AI Resident at Google X. With an M.S. in Statistics and a B.S. in Math and Computer Science from Stanford, my background spans pure math, reinforcement learning, and natural language processing. I’ve contributed to research and projects ranging from neural machine translation to autonomous RL for robotics.
