My name is Zhongtian Zheng and I am currently working at LightSpeed Studios.

I obtained my M.Sc. degree from the School of Computer Science, Peking University, under the supervision of Prof. Guoping Wang. I received my Bachelor’s degree from the School of Mathematical Sciences at Peking University in 2021.

My research interests focus on Computer Graphics, especially on geometry processing, real-time rendering, and physics-based simulation. I also have experience in computer-aided design, remote sensing, and visual localization.

We are actively looking for research interns. If you are interested in doing a research internship at Tencent Games, please drop me an e-mail with your CV and a short summary of your research interests.
