I am currently a Physics Engine Development Engineer at Tesla Optimus🤖 in Palo Alto, CA. I graduated and received my Ph.D. degree from Kahlert School of Computing, the University of Utah in 2026. I was co-advised by Professor Jenny Lin and Professor Cem Yuksel. Before that, I was advised by Professor Yin Yang.

I grew up in Shanghai, China, and received my Bachelor’s Degree in Computer Science from Peking University, China in 2020. Before moving to the U of U and changing my research area to computer graphics in 2022 Fall, I was studying computer networks at Georgia Tech.
