Research Statement

The fate and transport of contaminants in aquatic systems is intertwined with the fate and transport of colloidal materials (biological and non-biological particles in the size range of several nm to several um). Biological colloids include protozoa, bacteria, and viruses; whereas non-biological colloids include mineral precipitants, manufactured colloids, and engineered nanoparticles. Contaminant and colloid fate and transport in the environment is a scientific pursuit that lies at the interface between hydrogeology, geochemistry, biology, and engineering.
