My first 20 years were devoted to investigating the effects of different types of exercise training on physical performance, body composition, and cardiorespiratory health. Since the mid-1990s, I've focused on understanding physical activity and eating patterns as modifiable health behaviors. Publications include over 70 peer-reviewed articles and three textbooks including iHealth: An Interactive Framework, now in its 3rd edition (McGraw-Hill, 2016). In addition to being a professor at Georgia Tech for three decades, I was a Fulbright Scholar at the University of Cape Town Medical School (South Africa), a Senior Scientist at the CDC (Atlanta), and a Visiting Research Professor in the School of Population Health at the University of Queensland (Australia). Professional societies: elected Fellow of the American College of Sports Medicine, Research Consortium of SHAPE America, Society of Behavioral Medicine, and National Academy of Kinesiology. In 2018 I published The Sneakers in the Closet and Other Essays, my first venture in narrative nonfiction (for more information go to Amazon).
