The Equine Network Epidemiology and Biosecurity Team @ the Ontario Veterinary College

Thank you for your interest in our equine research projects!

The Equine Network Epidemiology and Biosecurity Team is co-led by Dr. Amy Greer and Dr. Terri O'Sullivan in the Department of Population Medicine. 

We do not currently have any projects open for enrolling participants. If you would like to be informed when we are starting new equine research projects please let us know so that we can add you to our mailing list by contacting:

In the meantime, you can browse information about our past projects as well as read media stories about our work below.
