Thatcher received his MS, DVM and PhD (Nutritional Physiology) from Iowa State University in 1977, 1981 and 1982, respectively. He is a Diplomate of the American College of Veterinary Nutrition. After graduation, he spent several years in private mixed-animal practice in north central Pennsylvania. His research interest is in the area of comparative nutrition and the role of antioxidant nutrients in health and disease, particularly as it relates to obesity and insulin resistance. He was Co-Director of a multidisciplinary $3.25M NSF-IGERT award titled “Macromolecular Interfaces with Life Sciences: Oxidative Processes” at Virginia Tech. He has mentored over 30 graduate and post-doc students, has been awarded over $6M in research funding during his career, and has published over 125 peer-reviewed papers. Thatcher has been a frequent invited speaker at national and international professional conferences. He has co-authored and co-edited the textbook, Small Animal Clinical Nutrition, which is the most widely used textbook to teach small animal clinical nutrition to practitioners and veterinary students worldwide.

My research has focused on using animal models to study important human and animal diseases, specifically the role that nutrition plays in disease processes. I have been involved in both basic and translational research and funding for my work has been from various sources including federal agencies, industry, and private foundations. Most recently, my research has focused on oxidative processes as it relates to obesity and asthma using an equine model.
