About

I am a Ph.D. working with Prof. Chongjie Zhang and Prof. Yang Gao at Institute for Interdisciplinary Information Sciences, Tsinghua University, headed by Prof. Andrew Yao. I received my B.Sc. degree in Theoretical and Applied Mechanics from Peking University in 2019, with a double major in Computer Science. During my Ph.D., I was fortunate to visit Northwestern University and work with Prof. Zhaoran Wang .

My primary research goal is to build intelligent and autonomous agents and deepen the understanding of our own intelligence. Toward this goal, my research interest has been focused on designing algorithms for decision-making in a principled and data-driven approach, which are essential for agents to act and learn effectively in complex environments. Current directions I am working on include offline reinforcement learning, reinforcement learning with foundation models, and reinforcement learning theory.

Please feel free to contact me if you are interested in collaborating with me.
