Dr. Matthew Riddle is an Assistant Energy Scientist in the Energy Systems and Infrastructure Analysis division at Argonne National Laboratory.
His research interests include agent-based modeling and other computer simulation techniques to model complex energy and economic systems.
Since 2012, he has been the lead developer of Argonne’s GCMat, an agent-based market model of global critical material supply chains. GCMat has been used to support analysis for the U.S. Department of Energy’s Office of Policy and for the Defense Logistics Agency’s biannual report on strategic material stockpile requirements.
Riddle’s other work includes modeling combined PV and battery systems, evaluating the economic impacts of COVID-19, and projecting adoption trajectories for manufacturing technologies.
