About Me

I am a phd student in Department of Computer Science of Purdue University. My advisor is Professor Ninghui Li. I am a member of TruSe lab and CERIAS center.

Before I came to Purdue, I got a bachelor's degree in Computer Science & Technology at Tsinghua University in 2004.

Research

I am interested in various areas of information security, especially access control.
