Research Interests

My research interests include infectious and metabolic diseases of dairy cattle, including particular interest in Johne’s Disease, bovine mastitis and bovine lameness. Over the last 25 years I have worked closely with dairy producers, dairy producer organizations and veterinary practitioners in developing field-based research projects that address practical issues of concern to the Canadian dairy industry. I am particularly proud of my long-standing research partnership with Dairy Farmers of Ontario and Lactanet and work that we have done to validate and implement milk based tests for Canadian dairy farmers.

Teaching

I teach in the DVM and graduate programs at the University of Guelph.  My DVM program teaching focuses on aspects of evidence-based veterinary medicine, infectious disease control and dairy health management.
