A. Welford Castleman Jr., the Evan Pugh Professor of Chemistry and Physics and Eberly Family Distinguished Chair in Science.
Castleman's research focuses on small clusters of molecules. In particular, he is interested in why nanoscale matter behaves differently from large-scale matter. His group created the first Metallo-carbohedrenes, or Met-Cars, which are combinations of carbon and metal atoms expected to have applications as catalysts, superconductors, or the quantum wells in semiconductor devices.
