Research Interests / Areas of Expertise:
My research interests are in the areas of preharvest food safety, bacterial colonization mechanisms, zoonotic transmission of bacterial pathogens, pathogenesis of enteric E. coli diseases, and the microbial ecology of gastrointestinal systems. Current projects are focused on colonization mechanisms of E. coli 0157:H7 in ruminants and the pathogenesis of edema disease in piglets.
