My current research focuses on impulsivity as a trans-disease process in adolescent health risk behaviors. Specifically, I am interested in how impulsivity and other family, process and psychosocial factors interact to affect prevention and treatment outcomes for adolescent addictive behaviors. My primary research examines factors related to the initiation and maintenance of tobacco smoking in children and adolescents in order to inform and develop effective treatments for these behaviors. My secondary research line extends the knowledge gained from adolescent addiction research to eating behavior and obesity in adolescents. In both areas of research, I am also studying the neural mechanisms that underlie performance on laboratory behavioral tasks modeling impulsive behaviors in order to better inform prevention and treatment interventions.
In addition to my own lines of research, students in my lab are examining the role of impulsive behavior in the initiation and maintenance of other behaviors such as risky sexual behavior, disordered eating, video game use, and recovery after chronic illness.
Our laboratory is the Health Behavior Research Group (HBRG). HBRG is a 9-room, state-of-the-art, community-based clinical research laboratory located in the heart of the Bryan-College Station metropolitan area. HBRG is uniquely organized to support the full spectrum of clinical research, from human laboratory models to large-scale treatment-outcome studies. HBRG faculty, staff, graduate students, and undergraduate research assistants are actively engaged in collaborative research projects with local schools, health agencies, and medical specialists.
