Research Interests

Our current and future research plans are directed towards elucidating the molecular basis of inherited diseases in companion animals. We are interested in developing tests to help breeders eliminate inherited diseases in dogs and horses. A large number of the diseases seen in veterinary practice that affect purebred animals have a heritable basis. Characterizing inherited diseases in dogs has the added benefit of providing an animal model for human diseases. Presently we have projects in both the horse and the dog.
