About Me

Hi there! I am a Computer Science PhD candidate and NSF Graduate Research Fellow at the University of California, Irvine. My research involves the integration of brain-inspired computing paradigms to popular deep reinforcement learning algorithms. Prior to my graduate studies, I worked as a full-stack software engineer in the FinTech space.
