Profile

I am a Postdoctoral Fellow in the Department of Computer Science and Engineering, The Chinese University of Hong Kong (CUHK), collaborating with by Prof. Michael R. Lyu. I am interested in all software security and reliability issues, especially those related to man-at-the-end (MATE) attacks. Currently, I am working on a project Fusor, which is an obfuscation tool based on LLVM. Besides, I am also interested in the reliability problems of machine learning systems.
