About me

Hi! I’m a second-year PhD student at Institute of Computing Technology, Chinese Academy of Sciences (ICT, CAS), fortunate to be advised by Prof. Fei Sun. Previously, I obtained my B.E. in Software Engineering from Nankai University. My research interests include Knowledge Editing, Knowledge Mechanism of LLMs, and Trustworthy AI.
