I am a PhD Candidate in Computing + Mathematical Sciences at Caltech. I do machine learning with Professor Yisong Yue.

I’m interested in sequential decision problems: specifically, how to efficiently integrate domain knowledge and structure into data-driven methods . My research overlaps with reinforcement learning, imitation learning and optimal control.

I’m fortunate to spend previous two summers at Microsoft Research in NYC and Disney Research in Pittsburgh. I’m currently supported by an Amazon AI Graduate fellowship.

News & Announcements

• I gave a tutorial on Imitation Learning, together with Professor Yisong Yue at the International Conference on Machine Learning (ICML) in Stockholm in July 2018
• I'm TA-ing an advanced topics course at Caltech with a special focus on reinforcement learning
