Junwoo Chang

I am an incoming Ph.D. student in Mechanical Engineering at UC Berkeley, where I will be advised by Prof. Negar Mehr. I obtained my M.S. and B.S. at Yonsei University under the guidance of Prof. Jongeun Choi. My research focuses on robotics and reinforcement learning, especially on developing sample-efficient, generalizable, and theoretically grounded methods.
