About me

Hi! I am currently a Ph.D. student at Georgia Tech, majoring in Computer Science, advised by Prof. Bo Zhu in Computer Graphics Lab.

My research focuses on machine learning for physical and geometric modeling. I develop differentiable representations and neural operators for physics-based simulation, geometric computing, and generative 3D modeling.

Previously, I received my bachelor’s degree from Huazhong University of Science and Technology (HUST) and my M.S. in Computer Science from Dartmouth College.
