I am interested in solving applied problems related to how agriculture impacts environmental and human health. My research focuses on using animal manure as a fertilizer while minimizing adverse environmental and human health impacts.
Major Project Activities
My current projects address issues associated with pathogens and antibiotic resistance from agricultural settings. I characterize how bacteria and genes from animal manures travel through agricultural production systems, soil, and water. My main projects involve studying the fate and transport of pathogens, fecal indicator organisms, antibiotic resistant bacteria and antibiotic resistance genes, in runoff from feedlots and runoff from manure-amended fields. I use the tools of microbial ecology to profile microbial communities, and determine how “problem” microbes or “problem” genes interact with all of the naturally occurring microflora in agriculturally impacted environments.
