I am a Lecturer in the College of Computer Science and Technology at Hangzhou Dianzi University, China. I received my Ph.D. from the State Key Laboratory of CAD&CG at Zhejiang University, advised by Prof. Hujun Bao and Prof. Weiwei Xu. I received my M.S. from Nanjing University and my B.Eng. from Shandong University of Science and Technology. I was awarded the Excellent Ph.D. Dissertation Award of Zhejiang University in 2022, and our work on transparent object reconstruction received an Best Paper Honorable Mention at Computational Visual Media Journal (CVMJ) 2025 .

Research interests: 3D reconstruction and understanding, neural rendering, inverse rendering, and image-based rendering.
