Yiheng Zhang 张一恒

I am a first year PhD student at Intelligent Graphics Lab at Hong Kong University of Science and Technology (HKUST), supervised by Professor Yuan Liu. I am also a research scientist intern at Tencent Games AI Center, collaborating with Professor Cheng Lin, Wenping Wang and Le Wan.

Previously, I received my M. Eng. degree from National University of Singapore. I also worked as a research intern at Tsinghua University with Researcher Yuwang Wang and Academician Qionghai Dai. I am truly fortunate that my interest in computer graphics was sparked and nurtured under the guidance of Professor Mirela Ben-Chen at the Center for Graphics and Geometric Computing in Technion - Israel Institute of Technology.
