I am an Assistant Professor in the College of Computing at Georgia Tech. My research focuses on the security of mobile systems, with a concentration on telecommunications infrastructure and mobile devices. My research has uncovered critical vulnerabilities in cellular networks, made the first characterization of mobile malware in provider networks and offers a robust approach to detecting and combatting Caller-ID scams. I am also interested in Internet security and the systems challenges of applied cryptography.
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). I am also a co-founder of Pindrop Security.
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.
