I am with Carnegie Mellon University, as the Associate Director of the Information Networking Institute, where I also serve as a faculty. I am in addition a CyLab Systems Scientist, and have courtesy faculty appointments in the Electrical and Computer Engineering and Engineering and Public Policy departments. I am Faculty Advisor for a number of INI programs: Kobe Master's of Information Technology-Information Security (MSIT-IS), Athens Master's of Information Networking, and Master's of Information Security, Technology, and Management (MSISTM). I am also a core faculty in our Carnegie Mellon Usable Privacy and Security Doctoral Training Program, supported through an NSF IGERT grant. I received a Diplôme d'Ingénieur (1999) from École Centrale de Lille, a Master's (2000) and a Ph.D. (2003) in Computer Science from the University of Virginia. In the final year (2002-2003) of my Ph.D., I was working at Nortel. I then spent two wonderful years (2003-2005) as a postdoctoral fellow in the School of Information at UC Berkeley, before joining Carnegie Mellon in July 2005. I was a faculty in residence for three years (2005-2008) in our research and education center in Japan, CyLab Japan, located in Kōbe, which remains one of my favorite cities
