About me
I am a postdoc researcher at the Hong Kong University of Science and Technology, supported by the HK RGC Postdoctoral Fellowship Scheme (PDFS).
I obtained my Ph.D. degree supervised by Prof. Shuai Wang at the Department of Computer Science and Engineering, HKUST, in 2023. Before joining HKUST, I received my B.Eng. degree from Nankai University, Tianjin, China in 2019.
My research currently focuses on Reverse Engineering, my research interests include Computer Security and Software Engineering.
