I am a Ph.D. student at Peking University, advised by Prof. Peng-Shuai Wang. I received my B.S. degree from the School of Electronics Engineering and Computer Science at Peking University in 2024.
My research interests lie in 3D Generation and Computer Graphics, with a focus on developing efficient representations and generative models for high-quality 3D shape synthesis.
