OverviewAI-generated summary
Dr. Steven L. Foley directs the Division of Microbiology at the FDA National Center for Toxicological Research (NCTR) and holds the designation of Senior Biomedical Research and Biomedical Product Assessment Service expert. His academic background includes a Bachelor of Science in Zoology and a Ph.D. in Cellular and Molecular Biology/Infectious Diseases from North Dakota State University. He completed a postdoctoral fellowship at the FDA Center for Veterinary Medicine, focusing on developing methods for tracking the sources of Salmonella in food-animal species.
Dr. Foley's research at NCTR, which began in 2009, centers on zoonotic diseases, food safety, and the microbial assessment of FDA-regulated products. He has published extensively, with a h-index of 42 and over 6,000 citations across more than 180 publications. His work includes investigations into the population dynamics and pathogenicity of Salmonella enterica serotypes in commercial egg and poultry production, as well as their prevalence and potential pathogenicity in swine and poultry. He has also explored the characterization of Salmonella enterica Serotype Newport isolated from humans and food animals, and the application of molecular techniques to the study of hospital infections.
His professional development includes completing the Leadership Arkansas program and the Leadership in a Democratic Society program. Dr. Foley is also an Adjunct Professor in the Cell and Molecular Biology graduate faculty at the University of Arkansas and is a Fellow of the American Academy of Microbiology. He has collaborated on numerous publications with colleagues at the National Center for Toxicological Research, including Sung Guk Kim, Dereje D. Gudeta, Bijay K. Khajanchi, and Ohgew Kweon.
