Description of Research Interests

  • Dr. Doyle's research is in the area of food microbiology and focuses on bacterial foodborne pathogens.
  • Pathogens under study include Escherichia coli O157:H7 and other serotypes of enterohemorrhagic E. coli, Salmonella spp., Campylobacter jejuni, and Listeria monocytogenes.
  • Development of competitive exclusion treatments to reduce/eliminate carriage of E. coli O157:H7 by cattle, carriage of Salmonella spp. and Campylobacter jejuni by poultry and presence of L. monocytogenes in biofilms in floor drains of food processing plants.
  • Development of treatments for inactivation of pathogens on produce, meat, and poultry.
  • Evaluation of manure as a vehicle for pathogen contamination of produce.
