Dr. Mitchell was appointed interim dean of LSU Vet Med effective May 18. He had been serving as head of the Department of Veterinary Clinical Sciences and a professor of equine surgery. Dr. Mitchell joined LSU in 2005 as an assistant professor of equine surgery. He was then promoted to associate professor in 2011 and to full professor in 2018. Dr. Mitchell has practiced equine surgery in the LSU Veterinary Teaching Hospital, taught extensively across the DVM curriculum, mentored interns and residents, and developed a strong research portfolio in equine orthopedics and related areas.
In addition to his work as a clinician, educator, and researcher, Dr. Mitchell has taken on increasing leadership responsibilities within the school. From 2020 to 2023, he served as medical director for large animals at the Veterinary Teaching Hospital, working closely with the medical director for small animals to manage a complex, 24/7 clinical enterprise. In 2024, he was appointed VCS department head, taking on responsibility for faculty affairs, including promotion and tenure, the departmental budget, and the continued growth and success of one of the school’s largest academic units.
A graduate of the University of Edinburgh (BVM&S) and the University of Minnesota (MS), Dr. Mitchell is a diplomate of the American College of Veterinary Surgeons.
