About Me

I completed my Ph.D. (2024–2026) at the University of Nottingham with early graduation (2.5 years), supervised by Prof. Xiangjian He and Prof. Rong Qu. Prior to that, I worked as a research assistant at the Chinese University of Hong Kong, supervised by Prof. Zhen Chen and Prof. Yixuan Yuan. I received the M.S. degree from The University of Hong Kong in 2023, and the B.S. degree from the University of Lincoln in 2021 with First Class Honours.

Research Interests

Currently, my research interests primarily lie in Medical Image Analysis, Image Segmentation, and the application of Foundation Models in clinical diagnosis.
