I am an Assistant Professor in the College of Computing at Georgia Tech. I earned my Ph.D and M.S. in Computer Science and Engineering from the Pennsylvania State University in 2008 and 2004, respectively, and my B.S. in Computer Science from the University of Richmond in 2002. I am currently a member of the Georgia Tech Information Security Center (GTISC) and a co-director of the Converging Infrastructure Security Laboratory (CISEC).
My research focuses primarily on security in cellular networks. In particular, I explore the problems that arise as this piece of critical infrastructure is beginning to converge with the larger Internet. However, I am also interested in the systems challenges of applied cryptography and security for the Internet, mobile devices and wireless systems. In general, I am curious in learning about how secure systems are designed, constructed and broken.
Note: I am always looking for strong students with an interest in network security. Students must have a strong technical background, be comfortable with systems work and be prepared to work hard. If you are not a student at Georgia Tech and are interested in my research, please apply to the program.
