Carol Gillis, DVM, PhD, Dipl. ACVSMR, is a graduate of UC Davis School of Veterinary Medicine. She was the owner of a sport horse practice for 8 years during which time she became one of the first equine practitioners to perform ultrasound examinations on the musculoskeletal system of horses. Dr. Gillis returned for an equine surgery residency at UC Davis. Following completion of the residency, she obtained a PhD in equine tendon and ligament pathophysiology. Concurrently she established the equine ultrasound service at UC Davis, pioneering ultrasound of the musculoskeletal system at the University, and developing courses and wet labs to train terinary students, residents and veterinarians how to perform and interpret ultrasonographic examinations. She is the author of over 50 scientific publications in journals such as the American Journal of Veterinary Research and the Journal of the American Veterinary Medical Association on the subject of equine soft tissue injury diagnosis and treatment, and recently was an author of Equine Sports Medicine and Surgery, the definitive reference book on the topic. Clinically, Dr. Gillis has performed more than 22,000 ultrasound examinations of the horse and subsequently guided treatment of problems identified.
