    About Me

    Research Interests

    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. We 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.

    Courses

    I teach the following courses every fall semester:
    • ASM (ERM) 309 Measurement & Monitoring of Hydrologic Systems (3)
    • BE 467 Design of Stormwater and Erosion Control Facilities (3)
    For information about courses please visit the LionPATH Course Catalog.

    EDC Footprint Calculator

    Products we use in our everyday lives can be a source of endocrine disrupting chemicals in the environment. Download our Endocrine Disrupting Compounds Footprint Calculator to estimate the amount of EDCs in your personal care and household products.
