Dr. Fleming is a Fellow at the Homeland Security Studies and Analysis Institute.  His work focuses primarily on cybersecurity issues. These issues include cyber-physical convergence in critical infrastructure protection, measuring cybersecurity and public-private partnerships in cyber information sharing (econometric methods and performance measures), national cybersecurity strategy, government-industry collaboration, and legal authorities and their implications. 

He joined HSSAI from the U.S. Department of Defense, where for several years he directed a number of cybersecurity workstreams as a “Highly Qualified Expert” within the Office of the Assistant Secretary of the Army for Acquisition, Logistics and Technology. 

An occasional consultant to the International Monetary Fund (where he worked earlier in his career), Fleming is also an adjunct professor at Georgetown University’s Public Policy Institute, where he teaches graduate courses on risk management and strategy. 

He holds a doctorate in public policy from the University of London (University College London), a master of public policy from the University of Michigan (Ann Arbor), and a bachelor degree in American studies from Yale University.
