I was raised on my family's commercial cow-calf ranch in Montana. I acquired a BS in mechanical engineering from the University of Washington and a DVM degree from Washington State University. I specialized in beef and dairy practice in the northwest for five years and completed the MBA core courses at the University of Washington before returning to the University of Minnesota for a Ph.D. in veterinary epidemiology and production medicine with an outside concentration in agricultural economics.After three years as an assistant professor at the Veterinary Medicine Teaching and Research Center of the University of California, Davis, I moved to WSU where I have a research and teaching appointment split between the agriculture and veterinary colleges. My teaching interests are clinical epidemiology, evidence-based medicine, outbreak investigation and bovine production medicine.

Specific Research Areas
My research interests are the epidemiology of infectious and of production diseases of the bovine, including those that have zoonotic and food safety aspects. I am board certified in veterinary preventive medicine (ACVPM).
