Chong Zeng

I'm a master student majoring Computer Science and Technology at Zhejiang University, supervised by Prof. Hongzhi Wu. During my master, I'm fortunate to work closely with Dr. Yue Dong, Dr. Xin Tong and Prof. Pieter Peers as a research intern at Microsoft Research Asia and with Prof. Hao Su as a visiting graduate at UC San Diego. Before that, I received my bachelor's degree at College of Computer Science and Technology, ZJU.

My primary research interest lies in Computer Graphics, with a particular focus on creating high-quality 3D object assets for rendering. My previous work has centered on reconstructing and generating the appearance and geometry of these assets through data-driven methods.

I will finish my master in spring 2025, and I'm actively looking for PhD positions in fall 2025. Please contact me if you're interested!
