Shuichang Lai 赖水长

Email Google Scholar GitHub

I am an Algorithm Expert at the Taobao Technology Department, Alibaba Group. I received my M.S. degree in computer application from Nanjing University in 2023, advised by Prof. Jie Guo and Prof. Yanwen Guo. Before that, I received my bachelor's degree in computer science from NJUST.

My research interests lie at the intersection of computer vision and computer graphics, especially appearance modeling, material estimation, and 3D reconstruction.
