Dr. Slenning comes from a background of a Bachelor's degree in animal science, a graduate degree in nutrition & agricultural economics, a DVM, and another graduate degree in epidemiology. These were followed by eight years of private practice in California's southern San Joaquin valley -- the heart of California's dairy industry.

In late 1989 Dr. Slenning joined the NC State CVM faculty in dairy production medicine where he teaches to all four years of veterinary students, as well as undergraduate Animal Science students and graduate students. He is the coordinator of the Population Medicine Graduate Program and completed a five year assignment as the Associate Editor for the Elsevier journal, Preventive Veterinary Medicine, the flagship journal for veterinary epidemiology and quantitative research. In 2001 he helped create, and is the current Leader of, the College's Animal Biosecurity Risk Management Group, a service-oriented consulting group of veterinary agricultural-, environmental-, & public health-practitioners, epidemiologists, and risk-assessors aiming to assist our industries and profession in protecting the US food supply, improving animal welfare, and maintaining an economically sustainable American agriculture.

His main area of interest is in clinical/management decision theory and applications, where the main goal is to establish achievable goals, and rational priorities, and efficient methods to achieve those ends. In accomplishing this goal Dr. Slenning makes use of techniques from economic theory, operations research, clinical epidemiology, decision analysis, agricultural finance, diagnostic test evaluation, animal husbandry and management, and, last but not least, veterinary medicine. Dr. Slenning spends a good deal of time on the road giving talks and short courses to veterinarians, producers, and government decision makers on agriculture, dairy production medicine, risk management, disease programs, biosecurity, and bioterrorism.

Whether it is in individual animal case management, farm-level decision making, or regional animal health regulation, the importance of tying biology, economics, and rational decision making together into a valid and repeatable process for the herd manager, practicing veterinarian, or regional disease control expert, is Dr. Slenning's goal.
