My research focuses on the psychological and biological factors related to obesity and eating behaviors. The processes that control food intake and the regulation of food choices are topics that are poorly understood. It is well-known that psychological factors (e.g. emotional states) and cognitive brain functions (e.g. an area called the prefrontal cortex, which is mainly involved in self-control, reward processing and decision making) can influence appetitive behavior and weight change. In my lab, we are trying to understand how these behavioral and cognitive processes affect eating behavior and metabolic factors using behavioral questionnaires and neuropsychological performance tasks. Additionally, I have a long-standing interest in the study of binge eating disorder, the night eating syndrome, and the relationship between stress and eating.
