Our group is concerned mainly with structure and phase formation in non-equilibrium materials. Particular interests are in solidification of undercooled liquids, crystallization of metallic glasses, short-range atomic order and dynamics in liquid and amorphous metals, solid/liquid interfaces, and heterogeneous nucleation.
