Jiahui Lei 雷嘉晖

I'm a CS Ph.D Student (2020-now) at University of Pennsylvania. My advisor is Prof. Kostas Daniilidis. I'm currently studying the representations and algorithms for 3D and 4D geometric data to model our dynamic real world.

I received my B.S. degree (2016-2020) in Automation with ranking 1st/141 and with honors from Chu Kochen Honors College, Zhejiang University. Before that, I did Physics Olympiad in Dalian No.24 High School.
