In 2023 I joined the School of Animal and Veterinary Sciences (SAVS), bringing 32 years of experience in mixed veterinary practice, academia, diagnostic laboratories, government and industry. My role in SAVS comprises a balance of research, teaching and clinical service in the Roseworthy Veterinary Hospital's Pathology Laboratory.The constant themes of my career have been improving the health of farm animals, protecting public health and enhancing food security. Subthemes included veterinary pathology, pathogenesis of infectious diseases, immunology, laboratory diagnostics, vaccinology and biosecurity. My experiences have given me unique skills and perspectives about how emerging scientific knowledge and advanced technologies can be applied systematically to deliver solutions that have real world impact. 
 
I am a member of several professional organizations, including the American College of Veterinary Pathologists, the New Zealand Society for Veterinary Pathology, and the Australian Society for Veterinary Pathology.  I also serve as a trustee for the Massey University Foundation, Wildbase Research Trust.
