Bio
I am primarily interested in using molecular and microbiological tools to solve environmental problems. My research has covered a wide range of topics, some of which include: bioremediation of crude oil spills; probiotic Lactobacilli and their effects on the gastrointestinal ecology of weaning pigs; bioaugmentation of industrial waste streams; and fecal source tracking methodologies. My current interests are focused on fecal source tracking to improve water quality and effectively remediate chronic contamination issues. Ongoing research includes development of fiber-optic biosensor assays for use in field operations that target specific fecal bacteria and can identify sources of contamination in regard to host types (i.e. human vs. animal).
