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.
News:
December 9, 2011: I have been named the Co-Chair of the Program Committee for the Annual Computer Security Applications Conference (ACSAC) for 2012 and 2013.
October 18, 2011: Our paper, (sp)iPhone: Decoding Vibrations From Nearby Keyboards Using Mobile Phone Accelerometers, is being presented at the ACM Conference on Computer and Communications Security (CCS). This work, covered in a number of news outlets, demonstrates that a mobile device located near a keyboard can record information typed by a victim using only the phone's accelerometer.
September 27, 2011: I took part in the US-China Software Workshop in Beijing, a bilateral effort to encourage collaboration between researchers in the two countries.
August 8, 2011: I have been named the Program Chair for the 2012 USENIX Workshop on Hot Topics in Security (HotSec).
July 26, 2011: I will be an invited speaker at the East African Workshop on Cyberspace Security in Nairobi, Kenya. I will be discussing issues regarding cellular infrastructure security at this joint effort between the US Department of State and the governments of Burundi, Kenya, Rwanda, Tanzania and Uganda.
