Tiancheng Li's Homepage

I am a Ph.D. student in the Department of Computer Science and a member of CERIAS at Purdue University. My advisor is Prof. Ninghui Li, who is also the chair of my advisory committee. Other members of my advisory committee are Prof. Elisa Bertino and Prof. Chris Clifton. My research interests are Data Privacy and Security, Data Mining, and Applied Cryptography.

Before coming to Purdue, I got a B.S. degree in Computer Science from Zhejiang University in 2005.
