Claudio Cioffi-Revilla


Dr. Cioffi is University Professor Emeritus at George Mason University. He received his first doctorate in quantitative political and social sciences from the University of Florence, Italy, in 1975 and a second Ph.D. in mathematical models in International Relations from the State University of New York in 1979. From 1977 to 2019 he taught at UNC Chapel Hill, the University of Illinois at Urbana-Champaign, the University of Colorado-Boulder, and George Mason University, where he became the first Professor of Computational Social Science, founding chair of the Department of Computational Social Science, and founding director of the Center for Social Complexity (2002–2019).

His research interests include climate and human security, conflict modeling and deterrence theory, disasters and risk analysis, and social complexity theory and research. His current research projects include theory and applied research on multi-scale disasters in coupled human-artificial-natural systems (CHANS), climate change, and advanced formal methods for hybrid functions in complex systems. His research has been supported by DARPA, NSF, ONR, DHS, NCTC, and ODNI, among other agencies. He is a co-founder and first President of the Computational Social Science Society of the Americas (CSSSA), a member of the American Mathematical Society (operator theory), SSEER (Social Science Extreme Events Research), KSS (Knowledge Systems for Sustainability), and DOD OSD SMA, among other scientific and policy networks. As a Jefferson Science Fellow of the US National Academy of Sciences, he served as Senior S&T Adviser at the US Department of State/INR, and was a DNI’s Galileo Awards Finalist.

He has authored over one hundred peer-reviewed scientific and policy publications, including seven books, the most recent being Introduction to Computational Social Science: Principles and Applications, 2nd edition, pp. 600 (Springer, 2017). For more publications, click here.
