Research Interest

My research interests are at the intersection of production animal agriculture and public health at the population level - with an emphasis on dairy cattle. On-going projects are in the areas of transition cow health and performance, calf infectious diseases (especially zoonoses), and milk quality. I teach a variety of bovine herd health and epidemiology classes as well as provide consulting and clinical service for the dairy industry.
