Cheng Lin 林铖

Ph.D., Researcher

chlin@connect.hku.hk

I am a researcher in the field of 3D AIGC. I used to be a senior researcher at Tencent .
I received my Ph.D. in Computer Science from The Univeristy of Hong Kong (HKU), advised by Prof. Wenping Wang. I visited Visual Computing Group at Technical University of Munich (TUM), advised by Prof. Matthias Nießner. Before that, I completed my B.Eng. degree at Shandong University working on geometry and graphics. My research interests include geometric modeling, 3D vision, shape analysis and computer graphics.

I am a core member of AnySyn3D, a non-profit research interest group comprising individuals with a strong interest in exploring research problems and cutting-edge technologies in 3D AIGC.
