Jinnan Chen

I'm currently a Ph.D. candidate at NUS School of Computing, supervised by Prof Gim Hee Lee. I received my B.E. degree from Wuhan University and MEng degree from Nanyang Technology University with a GPA of 5.0/5.0. During my master's study, I was supervised by Prof Jiang Xudong and Dr Qian Zheng.

Currently, my research interests are mainly in Computer Vision and Generative Models, including 3D Generation/Reconstruction/Animation (Mesh & 3DGS & Rigging/Skinning), Multimodal Video Generation (AR & Diffusion) and Unified Models (Understanding & Generation). I did research internship at Bytedance AI Lab, Tencent Games and Hedra Labs.
