overview

Dr. H. Morgan Scott is a graduate veterinarian holding a PhD in epidemiology and post-doctoral training in public health. In addition to private veterinary practice, he has worked in both government (food safety surveillance) and academic settings. He is currently professor of epidemiology in the Department of Veterinary Pathobiology at Texas A&M University. He was recruited to Texas A&M University in 2014 as part of the Texas A&M University System Chancellor's Research Initiative and the University President's Initiative on One Health and Infectious Diseases. He relocated from Kansas State University, where he previously held the E.J. Frick Professorship in Veterinary Medicine. Much of his research emphasis has been on studying factors impacting antimicrobial resistance among commensal and pathogenic enteric bacteria in food animal production systems, with a program spanning the realm from the molecular to the sociological. In particular, he is interested in applying both epidemiological and ecological approaches to quantify the emergence, propagation, dissemination, and persistence of resistant enteric bacterial strains in integrated populations of animals, their food products, and humans. Using this knowledge, he hopes to identify opportunities to prevent and intervene against resistance among enteric pathogens in animal agriculture; preferably, by developing readily adoptable and cost-effective management practices suited to modern animal and food production systems.
