About me

Hi! I’m a first-year master’s student at the Institute of Computing Technology, Chinese Academy of Sciences (ICT, CAS), in the State Key Laboratory of AI Safety. I completed my undergraduate studies in Computer Science and Mathematics at the University of Chinese Academy of Sciences (UCAS). My current research interests focus on tool use in LLM agents and LLM uncertainty, alongside knowledge memory and updating in LLMs and trustworthy LLMs.
