Cheng Lin 林铖

Ph.D., Researcher, Tencent

chlin@connect.hku.hk

I'm currently a researcher at Tencent Game AI. I received my Ph.D. 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 did my bachelor's degree in Shandong University and was a Research Asistant at the Research Center of Digital Media Technology. My research interests include geometric modeling, 3D vision, shape analysis and computer graphics.

I'm looking for self-motivated interns who are interested in research problems in digital content creation in games. If you want to work with me at Tencent Games, feel free to drop me an email.
