Currently, I work in USTC as a Postdoc Research Fellow and work with Zhibo Chen. I have obtained my Ph.D. in MOE-Microsoft Key Laboratory of Multimedia Computing and Communication, University of Science and Technology of China (USTC), supervised by Zhibo Chen. Prior to that, I obtained my B.S. degree in Department of Electronic Engineering and Information Science from the University of Science and Technology of China (USTC). From Apr. 2021 to Apr. 2022, I was a research intern at Intelligence Media Group of MSRA under the supervision of Cuiling Lan and Wenjun Zeng. I have been a visiting Ph.D. of Learning and Vision (LV) Lab at the National University of Singapore under the supervision of Xinchao Wang. My research interests mainly focus on image/video processing, transfer learning of foundational models, generation, and agent.
