Joining NREL in 2000, Craig Perkins is a senior scientist in the laboratory’s Interfacial and Surface Science group, where he works with photovoltaic and energy materials. He received a bachelor's degree in chemistry from the University of Florida in 1990, going on to study gas-phase chemistry of van der Waals molecules at the University of Central Florida. He switched gears to the solid state in 1992, investigating the surfaces of metal boride single crystals under the supervision of Professor Michael Trenary at the University of Illinois at Chicago. In 1998, the newly minted Perkins began a 2-year postdoctoral fellowship at the Environmental Molecular Sciences Laboratory, part of the U.S. Department of Energy's Pacific Northwest National Laboratory. There Perkins worked with Michael Henderson to understand chemical and physical processes that occur during photochemical reactions on surfaces of transition metal oxide crystals such as TiO2(110) and CeO2(111).
