- Professor and Director, Large Animal Clinical Sciences, School of Veterinary Medicine and Biomedical Sciences
Dr. Morley is an epidemiologist and veterinary internal medicine specialist that studies infectious diseases affecting animals and people. Major emphasis for his professional activities includes using analytical epidemiology to improve our understanding and control of diseases in animals and people, investigating the ecology of pathogens and antimicrobial resistance determinants in animals and food production systems, and using infection control and biosecurity to manage health risks that are important in veterinary medicine, agriculture, and public health. Most recently he has used metagenomic methods to investigate the effects of agriculture production practices on antimicrobial resistance and microbial ecology as these affect human, animal, and ecosystem health. In 2019, he was appointed the Director of Research for VERO - the Veterinary Education, Research & Outreach Program - in the College of Veterinary Medicine and Biomedical Sciences at Texas A&M University. In this role, he supports the growth of research programs for all VERO faculty, supervises and provides oversight for research staff and laboratories, and promotes research exposure programs for veterinary and undergraduate students. Previously, Dr. Morley served for 20 years as Professor of Epidemiology and the Director of Infection Control at Colorado State University's Veterinary Teaching Hospital. He is a recognized authority on infection control in animal populations and has consulted on infection control and biosecurity issues at veterinary hospitals, veterinary colleges, and animal production facilities around the world.
