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 a personal health textbook entitled iHealth, 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. Although retired from full-time academic life, I continue to work on projects that enable individuals and communities to adopt lifestyle behaviors that prevent and control chronic diseases.
