Upon completion of her veterinary degree at OVC, Dr. Windeyer went into rural mixed practice in Southern Alberta. She returned to the University of Guelph to complete her DVSc in ruminant health management and epidemiology. Her thesis examined vaccination and risk factors for bovine respiratory disease in dairy heifer calves. She won the D.F. Forster medal, University of Guelph's top convocation award for graduate students for academic achievement, motivation, leadership and citizenship. Dr. Windeyer volunteered for 5 months in Nepal with the Canadian Centre for International Studies and Cooperation, Veterinarians Without Borders, and the Lalitpur District Milk Producers Cooperative Union. Prior to returning to Canada, she spent 2 weeks trekking to Everest Base Camp and deworming yaks in the Khumbu Valley. Dr. Windeyer then joined UCVM in the Department of Production Animal Health.
