I am currently working in the Data Security Laboratory of the Institute of Information Engineering(IIE), Chinese Academy of Sciences (CAS) as a researcher(研究员) and doctorial tutor(博士生导师). I received my Ph.D. degree from the Institute of Computing Technology(ICT), Chinese Academy of Sciences (CAS) in 2014, and my M.S. degree from the Institute of Computing Technology in 2007, both in the area of information security. I currently lead a research team, the AI Security and Privacy Preserving Research Group, engaged in scientific engineering projects and research related to data security and AI security. My group includes 4 researchers and engineers, 12 Ph.D. students and 2 M.S. students.

We accept 2-3 new PhD and Master students every year, and we are also taking on interns, so if you are interested in secure multiparty computation, federated learning, and AI model security, please contact me.

My main areas of research include:

• Secure Multiparty Computation

  • Private Preserving Machine Learning(PPML), Private Set Intersection;
  • Secret Sharing, Garbled Circuit, Oblivious Transfer, Homomorphic Encryption

• Federated Learning and AI Security

  • Federated Learning with Non IID, Graph Federated Learning
  • Adversarial Sample, Backdoor Attacks
  • Secure Aggregation with Defending Byzantin Attack
  • LLM Security
