Colloids consist of at least two phases, one of whose dimensions are typically of sub-micron size. Research activities include both dispersed colloidal particles and materials formed from them. Areas of interest include the formation of core-shell particles, the thermodynamics and spatial arrangement of surfactants in multiple emulsions, and film formation from aqueous dispersions. Beyond film formation, studies are made on the influence of particle network microstructure upon macroscopic properties of films: these include strength, fracture resistance, and crack patterning.
