Assistant Professor

Biography

Chika C. Okafor, DVM, MS, PhD, DACVPM is a Pre-harvest Food Safety Epidemiologist. His research is primarily focused on identifying patterns of antimicrobial use/resistance in veterinary medicine. He has utilized his expertise in both qualitative and quantitative epidemiological methods as well as statistical analysis of large datasets to understand/prevent animal diseases (e.g., bovine anaplasmosis) and pre-harvest food safety issues (colibacillosis, salmonellosis) associated with use of antibiotics. He has published extensively in respected referred journals on antimicrobial use practices in livestock and on diseases that drive the increased use of antimicrobials in cattle. His long-term goal is to improve stewardship of antimicrobial use in food animals and veterinary medicine. Before joining UT, Dr. Okafor received his Doctor of Veterinary Medicine degree from the University of Nigeria, his Master of Science in Food Safety and PhD in Epidemiology both from Michigan State University, and did a post-doctoral fellowship in Nutritional Epidemiology at the University of Guelph, Canada. He is a diplomat of the American College of Veterinary Preventive Medicine and also has a specialty board certification in Epidemiology from the same college.
