My name is Jianchuan Chen（陈建川）, and I am a Researcher at Alibaba Group. My research interests lie in 3D Digital Human Reconstruction and Neural Rendering, with a particular focus on real-time talking avatars, neural radiance fields (NeRF), and 3D Gaussian Splatting. I aim to develop high-fidelity, real-time digital human technologies for augmented reality and interactive applications.
I received my M.Eng. and B.E. from Dalian University of Technology, where I conducted my research under the supervision of Prof. Huchuan Lu (IEEE Fellow) at the IIAU-LAB.
