About

I am a Ph.D. student at the School of Mathematics and Statistics, University of Melbourne, advised by Dr. Mingming Gong and Dr. Tingjin Chu. I received both my Bachelor's and Master's degrees from South China University of Technology, supervised by Prof. Dacheng Tao and Prof. Changxing Ding.

Currently, I am working on Diffusion Models for 3D generation. My previous work also involved 3D understanding.
