Makenzie Herzog, PhD, MPH is an Associate Epidemiology Director on the Sports Injury Surveillance and Analytics team at IQVIA, which examines injuries and player health in the NFL and NBA, and an Adjunct Assistant Professor in the Department of Exercise and Sport Science at the University of North Carolina at Chapel Hill. Her research interests include musculoskeletal and concussion sports injury prevention, use of large healthcare databases for assessing musculoskeletal injuries, and orthopaedic clinical research. Her methodological interests include use of surveillance, claims, and electronic health record data and adaption of existing epidemiologic methods to study sports injuries and musculoskeletal health.

Mackenzie completed her doctorate in Injury Epidemiology from the Department of Epidemiology at the University of North Carolina at Chapel Hill. She holds an MPH degree in Epidemiology from Emory University and a Bachelor of Arts degree in Psychology from Northwestern University.

Mackenzie has 16 years of clinical and research experience in sports medicine and orthopaedics, including previous positions at Steadman Philippon Research Institute, Northwestern University Intercollegiate Sports Medicine, Centers for Disease Control and Prevention, Children’s Healthcare of Atlanta, and Department of Exercise and Sport Science at the University of North Carolina at Chapel Hill. Mackenzie has published manuscripts in leading journals, such as JAMA Pediatrics, American Journal of Sports Medicine, and Journal of Bone & Joint Surgery, and presented her research at numerous clinical and epidemiologic conferences. She is an editorial board member for Sports Health, and was a co-chair of the planning and writing committee for the American Medical Society for Sports Medicine’s Youth Early Sport Specialization Summit. She has been an invited speaker for clinical education sessions on research methods in orthopaedics and sports medicine, thought leadership conferences on epidemiologic and public health methods for studying sports injuries, and clinical epidemiology courses.
