LI Heyuan

I am a Ph.D. student at The Chinese University of Hong Kong, Shenzhen, working on human-centric 3D computer vision and graphics, advised by Prof. HAN Xiaoguang. Previously, I obtained my M.S. from National University of Singapore, advised by Prof. Robby T. Tan. I received my Bachelor's degree from University of Electronic Science and Technology of China.

I believe simple is better than complex.

I (try to) practice Slow Science. Slow is faster than fast.

Research

My research goal is to develop a system that produces and drives high-fidelity 3D avatars in real-time using limited cost for everyone. My current research interests are mesh-based 3D face reconstruction and NeRF-based generic avatar learning from images.
