I am currently a Research Fellow at Cyber Security Lab, School of Computer Science and Engineering, Nanyang Technological University. I am working with Prof. Yang Liu on tackling challenging research problems in computer security. I received my Ph.D. degree from School of Cyber Science and Engineering at Wuhan University in 2022, under the joint supervision of Prof. Jing Chen and Prof. Ziming Zhao. Before that, I received B.E. degree from Xidian University in 2017.

My Research Topics:

• (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.
