About Yvette

Dr. Yvette Nout-Lomas is an associate professor of equine internal medicine and is boarded by both the American College of Veterinary Internal Medicine and the American College of Veterinary Emergency and Critical Medicine. Dr. Nout-Lomas is part of the team at CSU providing specialty care to horses. Her clinical interests include evaluation and treatment of horses with neurologic and behavior disorders and critically ill foals and adult horses. Her research goal is to improve diagnostic capabilities and treatment options for horses with neurologic disease. In particular her research is focused on gait assessment in horses, spinal cord injury, and comparative neuroscience.
