Research Interests: factors that influence ingestive
behavior and the development of obesity in humans, caffeine use
among adolescents, and exercise and nutrition interactions
Since 2008, I have been the director of the Nutrition and Health Research Laboratory. My students, staff and I work on research that is broadly related to ingestive behavior. We study factors that influence the motivation to eat and drink, the relationship between food additives (primarily caffeine) and behavior, and individual difference characteristics that predict weight gain in children, adolescents, and adults. We currently have funding from the National Institute on Drug Abuse to study the impact of caffeine use on behavior, physiology and mood in children and adolescents. We have also done extensive work on motivation to eat, including characterizing difference in lean and obese individuals in patterns of responding for food that predict later weight gain. In addition to our primary studies, we have done work on many other topics, including nutrition labeling, food pricing, hydration and energy intake, the influence of chewing gum on eating, and the relationship between exercise and eating.
