Ziqi Cai (蔡子祺)

About Me

I am a first-year Ph.D. student at the Camera Intelligence Lab, advised by Prof. Boxin Shi, at the School of Computer Science, Peking University. My research focuses on 3D vision and generative models.

As an undergraduate at the Beijing Jiaotong University, I interned at the Institute of Computing Technology, Chinese Academy of Sciences, and worked with Prof. Lin Gao, Prof. Hongbo Fu, Prof. Yu-Kun Lai, Kaiwen Jiang, and Shu-Yu Chen.

I am grateful to have received the Headmaster Scholarship at Peking University.
