ABOUT ME


I am currently a post-doctoral researcher at Department of Electrical and Electronic Engineering, The University of Hong Kong (HKU). I am working with Prof. Xianhao Chen on security and privacy for edge AI. Before joining HKU, I was a research fellow at Nanyang Technological University (NTU), working with Prof. Yang Liu on Web3 security. I received my Ph.D. degree at School of Cyber Science and Engineering, Wuhan University in 2022, under the joint supervision of Prof. Jing Chen and Prof. Ziming Zhao.

My research topics:

  • Security and privacy of distributed learning: explore new attack vector in distributed learning, and design the defense strategy to mitigate possible security issues.
  • (Large language model) LLM security: demystify underlying vulnerabilities of LLM, and design security systems founded on LLM.
  • Web3 security: monitor and identify potential financial risks in the Web3 era, such as money laundering and market manipulation.
  • Biometric security: mitigate security vulnerabilities of current biometric systems, and design usable and secure biometric authentication systems for mobile devices.
