Dr. Donoghue's research focuses on preharvest intervention strategies to reduce foodborne colonization of poultry (e.g. Campylobacter and Salmonella) and on developing predictive pharmacokinetic models of antibiotic and pesticide transfer in poultry. He also is interested in the potential interaction of veterinary drugs and pathogenic bacteria in the intestinal tract. His goal is to reduce the potential for drug and pesticide residues, and pathogens in poultry tissues.
