About

I am an Eric and Wendy Schmidt AI Postdoctoral Fellow at the AI for Science Institute, Cornell University, working with Fengqi You. I received my Ph.D. in Computer Science from the Institute for Interdisciplinary Information Sciences at Tsinghua University in 2025, advised by Chenye Wu and Ran Duan. From 2023 to 2024, I was a visiting student researcher in Computing and Mathematical Sciences at Caltech, working with Adam Wierman. I received my bachelor's degree in Computer Software Engineering from Huazhong University of Science and Technology in 2020.

Research

My research focuses on reliable and data-efficient reinforcement learning, optimization, and control for large-scale networked systems under uncertainty. I study how imperfect predictions, decomposable structure, and physical constraints can reduce what must be learned, leading to scalable algorithms with rigorous guarantees on sample complexity, performance, stability, and safety. I apply these ideas to power systems and grid-aware AI computing.
