Why do some people become obese while others remain lean? In my lab we investigate how individuals differ in appetite-related characteristics such as food cue responsiveness and satiety sensitivity, which predict body weight. To do this we use a range of methods including behavioral tests, questionnaires, genotyping, and brain imaging. We are currently using all of these tools to investigate familial and genetic risk for obesity in adolescents and children. Other research projects include studies of bariatric surgery, behavioral weight loss, binge eating, stress-related eating, circadian and hormonal influences on appetite, obesity prevention interventions, and medical conditions characterized by low appetite.
