About Me

My research interests center around the fate and transport of emerging contaminants. The land-application of biosolids and animal waste to agricultural fields as a nutrient source inadvertently introduces pharmaceuticals and personal care products (PPCPs) to the environment. These compounds can cause adverse impacts to fish and other sensitive aquatic species at trace concentrations as low as 1 ng/L. I seek to understand how the coupling of hydrology, biogeochemistry, and human activities affects the export of these compounds from agricultural fields to surface water bodies.
