My research focuses on environmental microbiology and biotechnology in the Department of Soil, Water, and Climate as well as the BioTechnology Institute at the University of Minnesota. The goal of my research is to solve key environmental problems, specifically (1) nitrogen pollution and (2) the occurrences of pathogens.
