Sergio Charles

I am pursuing an M.S. in Statistics at Stanford University, with a focus on artificial intelligence and machine learning. I have a B.S. in Mathematics and Computer Science. I have done research in pure mathematics, reinforcement learning and natural language processing. I am particularly interested in deep generative models and reinforcement learning for physical AI and scientific discovery.
