I received my M.S. and Ph.D. degrees in Computer Science from University of Illinois at Urbana-Champaign in 1996 and 1999, respectively. Prior to that, I received my B.S. degree in Computer Science from University of Science and Technology of China in 1993. After graduating from UIUC, I worked with Cisco Systems on network security for three years and helped starting a network security company, Protego Networks. I joined University of Florida as an assistant professor in 2002, and was promoted to associate professor in 2008 and to professor in 2013. I was a recipient of IEEE Communications Society Best Tutorial Paper Award in 1999, NSF CAREER Award in 2007, and Cisco University Research Award in 2007, 2012. I published 200+ peer-reviewed journal/conference papers and have 13 US patents. I hold University of Florida Research Foundation Professorship in 2017-2020 and University of Florida Term Professorship in 2017-2020. I am an IEEE Fellow and an ACM Distinguished Member. 

Openings: My research group has several opennings for research assistants. Please contact me if you have solid background in Computer Science  and are motived to pursue a Ph.D. degree for a research career.
