Chioke Harris is a Research Engineer at the National Renewable Energy Laboratory (NREL). As part of the Building Energy Science group, his research focuses on the application of fundamental heat transfer and materials science principles to the development of novel, high-performance building components. He is also involved in the development of energy efficiency impact analysis software, including ResStock, a highly-granular model of energy use in the residential building stock. Prior to joining NREL, Chioke was a AAAS Science & Technology Policy Fellow at the U.S. Department of Energy in the Building Technologies Office (BTO). In that role, Chioke co-created Scout, a software tool for evaluating the long-term energy and cost impacts of novel building technologies, and supported management of BTO’s windows and opaque envelope R&D portfolio. Chioke received his Ph.D. in Mechanical Engineering from The University of Texas at Austin, where his research examined the potential for plug-in electric vehicles to provide a firm, dispatchable energy storage resource on the electric grid. Chioke also holds an M.S. and B.S. in Mechanical Engineering from The University of Texas at Austin and Brown University, respectively.
