Jun Xiang (项 军)

I am a fourth-year Ph.D. student in Graphics & Geometric Computing Laboratory (GCL) at University of Science and Technology of China (USTC) supervised by Prof. Juyong Zhang, also a research assistant at The Hong Kong Polytechnic University (PolyU) guided by Prof. Defeng Sun and Yancheng Yuan. I obtained my B.S. degree in Mathematics in 2021 from USTC. And I undertook an internship in Image Derivative Inc. during Mar.2022-Jun.2023.

My research interests include but are not limited to:

• Human Avatar Reconstruction and Generation

• Head Avatar Modeling and Animation

• Neural Representation and Neural Rendering
