About Me

I am a Professor and the Associate Chair for Research in the Department of Information Sciences and Technology at George Mason University, and I serve as the Executive Director of the Institute for Digital Innovation (IDIA) and the Director of the Center for Infrastructure Security in the Era of AI (ISEAI). I received my Ph.D. degree in Computer Science and Engineering in 2005 from the University of Naples Federico II. In 2011, I joined George Mason University after serving as a Postdoctoral Researcher at the University of Maryland, College Park.

My research interests are in the area of Information and Network Security, with a particular emphasis on Modeling and Detection of Cyber Attacks, Cyber Situational Awareness, Network Hardening, Moving Target Defense, Configuration Security, and Vulnerability Metrics. I have participated in sponsored projects totaling $13M, with my personal share amounting to $3.5M. I hold six U.S. patents and have co-authored two books as well as over 90 publications in peer-reviewed journals and conference proceedings. In 2014, I was honored as one of the three recipients of the Mason Emerging Researcher/Scholar/Creator Award, one of the most prestigious honors at Mason.

I have served on the technical program committee of numerous conferences and am a member of the Editorial Board of Springer International Journal of Information Security, Elsevier Computers & Security, and IEEE Transactions on Dependable and Secure Computing.
