A specific focus of this portfolio was development of modular, scalable and reusable infrastructure to accelerate development, testing, and dissemination of evidence based interventions. Dr. McClain earned a BS and MS in Exercise Physiology from Iowa State University; a PhD in Physical Activity, Nutrition, and Wellness from Arizona State University; and an MPH from Johns Hopkins Bloomberg School of Public Health.
