Charles Xu

I am currently a research intern at Physical Intelligence Inc. Before this, I finished my undergrad at UC Berkeley in EECS in May 2024 , where I conducted research with Prof. Sergey Levine at the Robotic AI & Learning Lab. I've also had the pleasure of working with Stefan Schaal. My research interests lie at the intersection of robotics and machine learning, specifically developing more scalable and generalizable Reinforcement Learning and Imitation Learning methods for building robust and deployable robotic manipulation systems.
