Research Focus
Laboratory and field studies of sources and transmission of foodborne pathogensMolecular characteristics of foodborne zoonotic pathogensAntimicrobial resistance of enteric bcteria in the food supply chain
Specialty Focus
The overall goal of my research is to protect the health of animals and the public and food safety through laboratory and field-based studies on the sources, transmission, and molecular epidemiology of pathogens and bacterial antimicrobial resistance.
