Dr. Patrick Gerard Traynor

I am an Associate Professor in the Department of Computer and Information Science and Engineering (CISE) at the University of Florida. 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 received a CAREER Award from the National Science Foundation in 2010 and was named a Sloan Fellow in 2014. Click to learn more information about my research, publications and citations.

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. After promotion and tenure in the School of Computer Science at Georgia Tech, I joined the University of Florida in 2014 as part of the UFRising Preeminence Hiring Program. I am currently the co-director of the Florida Institute for Cybersecurity (FICS) and am also a co-founder of Pindrop Security.

Note: The University of Florida is building a world-class program in information security, and we are always looking for strong students. 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 the University of Florida and are interested in information security research, please apply to the program.
