Bill G. Kennedy

Associate Professor

Computational cognitive modeling, computational social science

Bill Kennedy is a Term Associate Professor in the Center for Social Complexity and the Department of Computational and Data Science at George Mason University in Fairfax, Virginia. He is a retired Navy Captain (30 years of service in submarines and the Naval Reserve) and a retired civil servant (25+ years with the Nuclear Regulatory Commission and the Department of Energy). He joined the Center for Social Complexity in 2008 after a post-doctoral fellowship at the Naval Research Laboratory sponsored by the National Academy of Science. 

Dr. Kennedy is a member of Sigma Xi, the American Association for the Advancement of Science (AAAS), and has been a member of the Association for Computing Machinery (ACM) and a life member of Institute of Electrical and Electronics Engineers. His research interests include:  integrating computational cognitive modeling and computational social science; cognitive plausibility; and autonomy.

Current Research

Dr. Kennedy is the PI for a 5-year project to characterize the reaction of the population of a mega-city. The project started in the summer of 2016 and is sponsored by the Defense Threat Reduction Agency (DTRA) at a rate of approximately $150K per year. The project is supporting a CO-PI, Dr. Andrew Crooks, and has supported four graduate research assistants.
