About Me

I am a PhD student in Control and Dynamical Systems at Caltech, where I am fortunate to be advised by Professors Yisong Yue and Joel W. Burdick. My research focuses on learning from human feedback, with applications to human-robot interaction and personalized medical therapy. I aim to develop theoretically-motivated, principled algorithms for learning from sequential human feedback. In addition, my interests include creating intelligent assistive devices, reinforcement learning, sequential decision-making, and applications of machine learning to healthcare. Outside of research, my other goals include positively impacting people’s lives through teaching and outreach.
