Biography

I am a fourth-year Ph.D. student at the Institute of Science and Technology for Brain-Inspired Intelligence (ISTBI), Fudan University, advised by Prof. Ningsheng Xu and co-supervised by Dr. Junjun He (GMAI Lab, Shanghai AI Lab). I received my B.Eng. degree in Intelligence Science and Technology from Xidian University in 2022.

My research interests include MLLMs, Agents and Low-level Vision for AI for Healthcare.

I am actively looking for collaborators and intern opportunities with a passion for AI!
