About Me

From 2002 until May 2008, I worked as a graduate research assistant under the guidance of my advisor Dr. Joseph B. Evans. My work included development of an agile or software-defined radio prototype developed by the agile radio group at the Information and Telecommunications Technology Center (ITTC). While working on the radio, I assisted in the development of a hardware prototype radio that operated in the 5 GHz UNII bands and developed cognitive engines that are to be used to "give life" to the radio.

My dissertation titled "Multiple Objective Fitness Functions for Cognitive Radios" explored multiple types of AI techniques for Cognitive Engines, and what environments different Cognitive Engines were more suited for. A Genetic Algorithm based engine was implemented and it's performance compared to a Rule-Based Cognitive Engine developed using the CLIPS Expert system engine.

Currently I am the Intelligence Community Post-Doctoral Fellow at Virginia Tech working in the area of Cognitive Radio Network Security. In addition to my security work, I manage several students and projects and I'm currently the lead on the VT Cognitive Radio Open Source System and Cognitive Radio Network Testbed efforts at Wireless @ VT.
