About Me

I am a postdoctoral researcher at the University of Science and Technology of China (USTC), working with Prof. Ligang Liu and Assoc. Prof. Xiao-Ming Fu. I received my Ph.D. from the School of Mathematical Sciences at USTC in 2025.

My research focuses on computer graphics, geometry processing, and optimization, including surface parameterization, developable surface generation, and physical simulation. I also work on generative AI, including large language models and graphics and video generation.
