MDR1 test through the Veterinary Clinical Pharmacology Laboratory

Research Interests

The driving force behind the research in my laboratory is the desire to prevent adverse drug reactions in veterinary patients. Adverse drug reactions increase not only patient morbidity and mortality, but add to the overall cost of veterinary care and to the emotional burden of the animal owner. Our research in veterinary pharmacogenetics has generated discoveries that truly are “bench to bedside” and are used globally to prevent adverse drug reactions in dogs (and is under development for cats). My laboratory is an integral part of the Washington State University Program in Individualized Medicine (PrIMe). WSU PrIMe researchers optimize drug therapy for individual patients and its faculty share their expertise via education and outreach activities for veterinarians, breeders and the pet-owning public.
