Paulo Costa has applied his significant experience as a fighter pilot to a career specializing in the field of electronic warfare and flight safety, which in conjunction with his research on probabilistic reasoning has led to applications in cyber and transportation security, heterogeneous data fusion, and decision support systems in healthcare, defense, and other areas. These topics are at the core of his classroom activities at both graduate and undergraduate levels, as well as his research path. 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.

Costa is a key researcher in the field of probabilistic ontologies and has developed innovative applications and extensions that aid in the fight against cyber-warfare. In addition to his Mason assignments as Interim Chair of the Cyber Security Engineering Department and Director of the C5I Center, Dr. Costa is Vice President for Securing Automation and Supply Chain Security ( He is a former President and current elected member of the Board of Directors of the International Society of Information Fusion (, as well as an IEEE Senior Member (SM13).
