My name is Tianhang Cheng (程天航), currently a 2nd-year PhD student (2024-) in the Department of Computer Science, University of Illinois Urbana-Champaign (UIUC), supervised by Prof. Shenlong Wang and Prof. Kaiyu Guan.

Before joining UIUC, I received my B.Eng. degree from Zhejiang University in 2022 with from Chu Kochen Honors Collage, where I worked with Prof. Xiaowei Zhou from May 2021 to May 2022.

My research interests lies in 3D reconstruction, 3D generation, parametric model, human motion, MLLM etc.
