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. I received B.E. degree at Xidian University in 2017. My current research interests include:

• Security and privacy of edge intelligence: [JSAC’24], [TIFS’24], [TIFS’23]
• Web3 security: [CCS’24], [ASE’24], [ICSE’24]
• Edge device security: [CCS’22], [USENIX Security’20], [TMC’24], [TDSC’24], [TDSC’21]
