Biography

I am an assistant professor at Shanghai Innovation Institute. I received my Ph.D. in computer science through a joint doctoral program between Fudan University and Shanghai Innovation Institute, advised by Prof. Han-Sen Zhong and Prof. Wanli Ouyang.

My research interests include computer vision & graphics (esp. world reality) and AI for science (esp. physics, medicine). I aim to let AI truly empower the physical world—understanding it while serving as its I/O, toward interactive and accessible intelligence.

Note: I'm looking for prospective Ph.D. students, research interns, and full-time engineers. If you're interested in lightweight 3D reconstruction/rendering, interactive/generative world models, optical/display engineering, please feel free to contact me.
