About Me

I am currently a first-year Ph.D. student supervised by Prof. Xingang Pan in MMLab@NTU. I obtained M.S. degree in Artifical Intelligence in 2023 from the school of computer science and engineering at Nanyang Technological University, advised by Prof. Chen Change Loy and Prof. Chongyi Li. I obtained B.E. degree in Information Engineering from Zhejiang University in 2021.

I am interested in computer vision and its applications in interdisciplinary field. My current work focuses on image decomposition and computer graphics. In the past, I have focused my reseach topics on image and video colorization, image enhancement and prompt learning.
