More Information


My research focuses on soil and water quality, nonpoint source pollution control, watershed management, and water quality monitoring. We use both lab and field scale studies to examine the occurrence, fate and transport of pathogens, pathogen indicators and contaminants of emerging environmental concern (CoEECs) such as antibiotics and antibiotic-resistant bacteria to surface and tile drainage systems.

Broader Impact

Findings from our work has implications to improve the Total Maximum Daily Load (TMDL) development and implementation process, identify the impact of landuse practices on water quality, and develop management practices to reduce pollutant transport. We work with landowners, commodity groups, and state and federal agencies to answer environmental questions and inform policy. Our goal is to protect public health and find ways to provide access to clean water to everyone.
