Pauling Fellowship Alumni

Dr. Grant Johnson

Grant Johnson — 2009 Pauling Fellow

Dr. Grant Johnson is a scientist in PNNL's Fundamental & Computational Science Directorate. His research is focused within the Separations, Detection, and Analysis program with Laboratory Fellows Dr. Julia Laskin and Dr. Yuehe Lin.

Dr. Johnson is developing unique capabilities for the preparation and high-throughput characterization of bi- and tri-metallic nanoparticles (NPs) of precise composition. His research is employing oxygen reduction and reduction of 4-nitrophenol as model reactions to investigate how the size, shape, elemental composition and support-interaction of alloy nanoparticles on surfaces influences their catalytic behavior. Utilizing these capabilities and fundamental insights into structure-reactivity relationships will allow the design of improved alloy nanoparticles for a broad range of applications in catalysis and energy storage.
