I’m a fifth-year Ph.D. student in Robotics at the University of California, Berkeley. I work with Prof. Masayoshi Tomizuka in the Mechanical Systems Control (MSC) Laboratory.

My research interest lies in the interdisciplinary combination of robotics, artificial intelligence (AI), and control theories with applications to robot contact-rich manipulation, robot skill learning, and learning for control.
