Dr. Kenneth D. Clinkenbeard is professor of veterinary pathobiology and coordinator of the Veterinary Biomedical Sciences Graduate Program at the College of Veterinary Medicine, Oklahoma State University where he teaches graduate and veterinary students and conducts research in the areas of infectious disease pathogenesis and ecology. Ken earned his PhD degree at The Johns Hopkins University School of Medicine in physiological chemistry in Albert Lehningerís department studying enzymology and was a NIH postdoctoral fellow under Nobel laureate in medicine Dr. Edwin G. Krebs at the University of California at Davis studying phosphorulation of glycogen synthase. While at UCD, he also earned his DVM degree. Dr. Clinkenbeard practiced veterinary medicine for eight years in a mixed animal practice in Redding, CA prior to coming to Olklahoma State University. He has over thirty-five years experience working with infectious diseases including disseminate histoplasmosis in dogs and cats; shipping fever, pinkeye, and E coli O157:H7 in cattle; tularemia and plague in wildlife; and chronic wasting disease in cervids. 

Fields of Interest:

Microbial pathogenesis; comparative microbial genomics; ecology of infectious diseases
