Short Bio

I am now a fourth-year Ph.D. student in the department of Information Engineering at the Chinese University of Hong Kong. I am fortunated to be advised by Prof. Sze Yiu Chau. My research interests span computer hardware and network security.

Before coming to CUHK, I obtained my M.E. degree from Fudan University under supervisor Prof. Zhe Zhou and got my B.S. degree in Computer Science and Technology from Ocean University of China in June 2019.
