Institute of Information Engineering, Chinese Academy of Sciences

I obtained my Ph.D. from the University of Chinese Academy of Sciences under the supervision of Professor Jingguo Ge. During my Ph.D. studies, I primarily focused on network traffic identification and tracking. After graduation, I worked at Huawei, where I had the opportunity to participate in projects related to information retrieval, which sparked my interest in LLM-based Agents, natural language processing, and large language models (LLMs). I am currently employed at the Institute of Information Engineering, Chinese Academy of Sciences, where I mainly conduct research in the field of large models. To date, I have published more than 10 papers in areas such as deep learning and LLMs, and I have served as a session chair or reviewer for several international conferences, including IJCNN and CIKM.

My research fields involve：

  • Large Model Agents Collaboration
  • LLM performance and security evaluation
  • Natural Language Processing
  • Blockchain
  • Traffic Classification
