About Me
Hi, I am Kaihang Ji, a final year Ph.D. student in Computer Science at the National University of Singapore, advised by Zhenkai Liang. I received my B.Sc degree in Computer Science at the Peking University in 2018.
My research interests lie in the interactions of system security. Specifically, I am working on binary analysis and audit log analysis.
