My research interests are in the biomechanics of quadrapedal locomotion, especially of the distal limb of the horse. My most recent research involves observing the effects of differing track surfaces, including moisture content, on the acceleration/deceleration patterns of the hooves of galloping Thoroughbred horses. I am no longer actively involved in research as I am now on a 100% teaching appointment.

My current teaching assignment includes an undergraduate course in veterinary anatomy, Functional Anatomy, in which we cover both histology and gross anatomy of domestic animals. A web-site has been, and continues to be, developed for the class ( to assist the students with the lab material. I am also the lead instructor in Veterinary Microscopic Anatomy and a co-instructor in Veterinary Anatomy I & II, the latter two courses being gross anatomy of small animals (primarily the dog) and large animals (primarily the horse and bovine) respectively.

Biographical Information

Patrick D. Wilson, after completing three years of undergraduate training in Zoology at Northern Arizona University, received his B.S. in Veterinary Science at Washington State University, following completion of the first year in the Veterinary Medical Program (1985). From 1985-90 he was a Research Assistant in Integrative Physiology and Neuroscience. In 1990 he earned concurrent degrees, an M.S. in Veterinary Science, emphasis in anatomy, and a Doctorate in Veterinary Medicine. In 1991 he worked as a veterinarian at a mixed animal practice in Glendale, Arizona. From 1992-94 he served as a Veterinary Clinical Associate in Pathology at Texas A&M University, where he was involved in a collaborative study which characterized the lesions of a hereditary nephropathy in English Cocker Spaniels. He joined IPN in 1997 as an Instructor and an Associate in Research. In the Fall of 2001, Dr. Wilson moved to a 100% teaching assignment as a clinical assistant professor of anatomy.
