Dr. Margo Macpherson received her DVM degree in 1990 from Michigan State University. She completed a residency and Master’s degree in Equine Theriogenology at Texas A&M University followed by practice at the University of Pennsylvania and central Kentucky. Dr. Macpherson is presently a Professor in the section of Reproduction at the University of Florida. She is interested in all aspects of equine reproduction, but has a special interest in problems affecting late pregnancy in the mare, most notably placentitis.

As a Diplomate and Past President of the American College of Theriogenologists, and most recently, the American Association of Equine Practitioners, Dr. Macpherson is dedicated to advancing equine/large animal veterinary medicine and supporting young veterinarians as they grow their own passion for the profession.

He performed his PhD, also at Cambridge, on 'Maternal Recognition of Pregnancy in the Mare' under the supervision of Professor W.R. 'Twink' Allen at the Equine Fertility Unit in Newmarket funded by the Horserace Betting Levy Board. After a short period as Lecturer in Animal Reproduction at Cambridge Tom moved to Utrecht University to become a lecturer in equine reproduction. In 2007, he was appointed to the Chair of Equine Medicine and Reproduction at the Department of Equine Sciences and also to an extraordinary Chair in Reproduction at the University of Pretoria, Department of Production Animal Sciences.

Tom is a Diplomat of the European College of Animal Reproduction (ECAR) and a Royal Dutch Veterinary Association specialist (KNMvD) in Equine Reproduction. He runs a busy clinical discipline working on all aspects of equine reproduction, with increasing emphasis on assisted reproduction and diagnosis and treatment of infertility. Tom's research interests are focussed on fertilisation, early embryonic development and early pregnancy loss in mares and in the relationships between semen quality and fertility in stallions. He is also involved in studies into semen quality and early embryonic development in farm animal and wildlife species and contraceptive techniques for the management of wild animal populations.
