DVM, Texas A&M University, 1997



Dr. Anne Wooldridge received her DVM from Texas A&M University in 1997 (Summa Cum Laude). She completed a rotating internship in large animal medicine and surgery, a residency in large animal internal medicine, and a Master’s degree at Louisiana State University. Her thesis projects investigated the effects of various drugs on smooth and skeletal muscle contractile function in the equine esophagus.

She completed a Ph.D. in the Department of Pharmacology and Cancer Biology at Duke University Medical School in Durham, North Carolina in 2005 and while there, was awarded a National Science Foundation Graduate Research Fellowship during her Ph.D. training at Duke University. Her dissertation research focused on calcium signaling in smooth and skeletal muscle using a transgenic mouse model.

She currently is an Associate Professor in Equine Internal Medicine where she sees clinical cases on the equine internal medicine service, and trains veterinary students, residents and graduate students.

She collaborates extensively with the Department of Chemical Engineering to evaluate the use of vascular progenitor cells and biomaterials for equine regenerative therapies. She also works with other researchers in the Auburn University College of Veterinary Medicine on both equine and small animal-focused projects.

She has authored or co-authored 28 journal articles and more than 45 abstracts. Dr. Wooldridge is board-certified by the American College of Veterinary Internal Medicine.

Research Interests


Endocrine and metabolic disease in horses, endocrinopathic laminitis, vascular disease, equine regenerative medicine, equine endothelial progenitor cells, smooth muscle disorders (feline respiratory disease, equine gastrointestinal motility). Her research in horses is primarily focused on vascular and metabolic disease in the horse, with special interests in laminitis and advancement of regenerative therapies in horses.
