Bio


I'm a highly motivated PhD student at MultiPLES Lab, UCLA Department of Mathematics, advised by Prof. Chenfanfu Jiang. Before that, I was a PhD student at Sig Lab, the University of Pennsylvania, working in the same group. I received my M.S. degree from the Department of Computer Science, the State University of New York at Stony Brook, and my B.S. degree from the Department of Mathematical Sciences, Tsinghua University (China).

My current research focuses on developing physics-based simulation models and applying machine learning techniques to enhance simulation accuracy and efficiency. I am also interested in sim2real/real2sim applications, which aim to bridge the gap between simulated environments and real-world systems.
