A researcher who coauthored atomic-scale studies of metallic nanoparticles using scanning transmission electron microscopy. An aberration-corrected instrument combined images of atomic columns with chemical analysis to investigate gold particles and particles containing two metals. This combination helps distinguish changes in shape from changes in composition, which can look deceptively similar in a single projection.[ref]
