He was made a Founding Fellow of the newly formed FIA Institute for Motor Sports Safety in Paris, and as such is actively involved in research on an international level.
Thomas Best, M.D, Ph.D.
Dr. Best is a board certified family medicine physician. Dr. Best provides comprehensive patient care using the latest advancements in sports medicine.
Michael Hoffer, M.D.
Dr. Hoffer began studying traumatic brain injuries while serving in the military in Iraq, with support from the Office of Naval Research, Army Medical Research and Materiel Command and the Department of Defense Hearing Center of Excellence.
His latest research capitalizes on the University of Miami’s experience in traumatic brain injury and collaboration between UHealth’s Otolaryngology Department and The Miami Project to Cure Paralysis.
Dr. Hoffer’s research focuses on early detection and level of severity measurements of mTBI in professional, college and high school athletes and personnel from U.S. military units outside of a hospital setting with the use of I-Portal PAS goggles. Currently, the main method of testing patients involves tests that are only available at medical centers. However, due to Hoffer and his team’s work, the I-Portal IPAS goggle has been outfitted with software that includes diagnostic tests that can determine, at the site of injury, whether the patient can return to the field or needs to seek further medical attention.
