About Me

I am a PhD student in Computer Science and Engineering Department at UC San Diego. My advisor is Professor Sicun Gao, and we are currently working on control and planning problems in robotics. I received my master degree in Applied Mathematics from National Tsing-Hua University. My master thesis focus on analyzing the stability of dynamical systems in mathematical biology.

Research Interests

Robotics, Nonliear Dynamical Systems and Control.
