About
Hi! I'm a second-year Ph.D. student at the Camera Intelligence Lab, Peking University, advised by Prof. Boxin Shi. My research focuses on 3D vision, physically grounded visual generation, and generative models — with a particular interest in bringing the physics of light into how models perceive and create images and video. Before Peking University, I received my bachelor's degree from Beijing Jiaotong University and interned at the Institute of Computing Technology, Chinese Academy of Sciences, where I was fortunate to work with Prof. Lin Gao, Prof. Hongbo Fu, Prof. Yu-Kun Lai, Shu-Yu Chen, and Kaiwen Jiang. I'm also grateful to have received the President's Scholarship at Peking University.
