My research group studies the fate of contaminants in natural and engineered systems with particular emphasis on sorption, the distribution of compounds between solid and water phases. We try to understand what unique characteristics of the compounds and the environmental system determine the magnitude of certain fate processes so that we can build predictive models. We have studied pharmaceutical compounds, endocrine disrupting compounds, combustion byproducts, solvents, arsenic and heavy metals in a variety of systems, including groundwater, surface water and drinking water.

I teach introductory courses in environmental engineering and environmental sustainability and specialized courses in water quality engineering, physico-chemical processes, environmental chemistry and water quality analysis.
