I am a CIS PhD student (Fall 2023 - Now) at the University of Pennsylvania, where I am advised by Prof. Lingjie Liu. I do research in computer vision and computer graphics. My research has been partly supported by Meshy AI Fellowship.

I did my undergraduate and master study in CS at Tsinghua University, working with Prof. Shi-Min Hu and Prof. Song-Hai Zhang.
