Dr. Duminda Wijesekera was named an Institute Fellow in June 2006. He is an associate professor in the Department of Information and Software Engineering at George Mason University, Fairfax, Virginia. During various times, he has contributed to research in security, multimedia, networks, systems, avionics, and theoretical computer science. Consequently, he draws upon his prior experience in addressing his current research issues. These span topics such as applying logical methods to access and dissemination control, securing SS7 and IP based telecommunication systems, multimedia, security requirements processing during the early phases of the software life cycle, WWW security, railroad signaling security, SADA security and engineering Ballistic Missiles. His pre-GMU work has been in quality of service issues in multimedia, avionics control and specifying and verifying concurrent systems using logical methods.

He holds courtesy appointments at the Center for Secure Information Systems (CSIS) and the Center for Command, Control and Coordination (C4I) at George Mason University, and the Potomac Institute of Policy Studies in Arlington, VA. He is also the director of liaisons at Aeolus Systems, an engineering services provider based in Clearwater, FL and Nashua New Hampshire.

Prior to joining GMU as an assistant professor in 1999, he was a senior systems engineer at Honeywell Space Systems in Clearwater, Florida. He has been a visiting post-doctoral fellow at the Army High Performance Research Center at the University of Minnesota, and an assistant professor of Mathematics at the University of Wisconsin. Dr. Wijesekera received a PhD in Computer Science from the University of Minnesota in 1997 and a PhD in Mathematical Logic from Cornell University in 1990.
