Principal Investigator-Greg LeFevre

I am an Assistant Professor of Environmental Engineering and Science in the Department of Civil & Environmental Engineering and IIHR-Hydroscience & Engineering at the University of Iowa. My research focus understanding the fate and biotransformation of emerging contaminants in non-point pollutants and how we can use engineered natural treatment systems to improve water quality. See the CEE webpage here.
