01About
I am a third-year PhD student at The University of Hong Kong, supervised by Xihui Liu.
Before that, I was an M.Sc. student in the MCG Group, Department of Computer Science and Technology, Nanjing University, supervised by Prof. Limin Wang (2020 – 2023), and received my B.Sc. in Software Engineering from Xidian University in 2020.
My research focuses on image / video generation and object detection.
