Our group uses experiments, analytical theory, and computer simulations to explore the processing-structure-property relationships in structural metals and materials, with particular emphasis on the role of structural disorder and its effect on mechanical properties. Our research covers many length scales, from long-range disorder in grain boundary networks, to the nanoscale disorder in amorphous and nanocrystalline alloys.
