About me

I am a first-year PhD student at Multimedia Lab (MMLab) in the Chinese University of Hong Kong, working with Prof. Xiangyu Yue. Previously, I was a master student at Beijing Institute of Technology (BIT), advised by Prof. Changsheng Li (2022-2025). I also received my Bachelor’s degree in Computer Science from BIT (2018 - 2022). I have published several papers in top conferences or journals, such as ICML, ICLR, NeurIPS, CVPR, KDD, ACL, IEEE TIP, IEEE TKDE, IEEE TPAMI, etc.

My research interests include Agentic AI, MLLMs and AIGC. Welcome for discussion and collaboration, feel free to drop me an email.
