Daniel Rafie, MD
UCLA Steve Tisch BrainSPORT Fellow ‘22

Dr. Rafie graduated with his Bachelors in International Affairs from James Madison University. He was inspired to pursue a medical degree after multiple medical services trips to Central America and Haiti in which he observed the positive effects of philanthropic medicine. He obtained his MD at the American University of the Caribbean, and completed his Neurology residency training at the Hackensack Health - JFK Neuroscience Institute in New Jersey.

As a result, he sought out additional training through multiple TBI elective rotations. The significant influence of sports in his life, his personal experience in concussion, and interest in working with high-risk groups and underserved populations led to his work on the concussion guidelines for the New Jersey Amateur Boxing Association and volunteer work alongside boxing ringside physicians. He was introduced to the field of Sports Neurology through an American Academy of Neurology article, and met Dr. Chis Giza at the Academy’s conference which brought him to the team. Dr. Rafie still practices his passion of sports playing basketball, surfing, and snowboarding. He also enjoys exercising and incorporates boxing and mixed martial arts to his workout regimens. He plans to become a certified ringside physician. Dr. Rafie’s main clinical and research interests include objective measures for concussion diagnosis, utilizing neurological therapies to enhance peak athlete performance, and the potential use of cannabidiol (CBD) as a therapeutic measure in treatment of concussion and traumatic brain injury. He looks forward to continuing his UCLA BrainSPORT fellowship while continuing his practice and research with a high standard of excellence and care.
