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.
