Costa is a key researcher in the field of probabilistic ontologies and developed innovative applications and extensions that aide in the fight of cyber-warfare. He is a Co-Director at GMU’s Radio and Radar Engineering Lab, and Director for International Collaborations at the Center of Excellence in C4I&Cyber. He received his MS and PhD from George Mason University.

Costa leads the research of graduate-level students in understanding security objectives and verification protocols, bringing in the science of probabilistic reasoning and challenging PhD level candidates to consider theory and methods for building computationally efficient software agents that reason, act, and learn in environments characterized by noisy and chaotic traffic.
