Research Focus

Polymer liquids are classified as complex fluids because their properties in external fields depend on a host of variables (e.g. the rate at which the field is applied, field strength, the spatial scale over which field strength changes, time, temperature, etc.). In virtually every case the source of complexity can be traced to the large size of the constituent molecules and to the finite time-scale on which they respond to change. My research group uses experiment, theory, and computer simulations to determine how physical chemistry of individual molecules and cooperative motion of large ensembles of molecules influence polymer properties in the liquid state.
