Charles H. Hillman, Ph.D., received his doctoral degree from the University of Maryland at College Park in 2000 and then joined the faculty at the University of Illinois at Urbana-Champaign, where he is currently a professor in the Department of Kinesiology and Community Health. He also holds appointments in the Department of Psychology, Department of Internal Medicine, Neuroscience Program, the Division of Nutritional Sciences, and Beckman Institute for Advanced Science and Technology. He directs the Neurocognitive Kinesiology Laboratory, which has the mission of determining lifestyle factors that improve cognition, maximize health and well-being, and promote the effective functioning of individuals as they progress through the human life span. Dr. Hillman has published more than 80 journal articles and 10 book chapters and has coedited a text on neuroimaging in exercise and sport sciences. His work has been funded by the National Institute for Child Health and Human Development, the National Institute on Aging, the National Institute of Diabetes and Digestive and Kidney Diseases, and Abbott Nutrition. Dr. Hillman’s primary research emphasis is to better understand factors that relate to increased neurocognitive health and effective functioning of individuals across the life span. He has predominantly focused on preadolescent children, with the goal of understanding how both single bouts of exercise and chronic physical activity promote basic changes in brain health that may lead to better cognition and scholastic performance. From a neuroimaging perspective, he has inves-
tigated the relationship of physical activity to underlying processes involved in attention, memory, and academic performance. Generally, results from this line of research have suggested that physical activity benefits cognitive operations during tasks that require greater amounts of goal-directed action, an effect that is less pronounced for other less-complex aspects of cognition. Accordingly, his research indicates that physical activity may have a greater influence on cognitive processes that are more effortful, rather than a general benefit to overall cognitive function.
