For the past 15 years, Dr. James Lock has been developing a research program for eating disorders in children and adolescents. Dr. Lock is an established scientist with over 200 publications including original peer reviewed articles, professional articles, book chapters, and books in the field. He has completed several NIH funded treatment studies and is currently involved as PI or Co-PI on three additional awards all focused on treatment interventions for eating disorders. Despite the relative frequency of anorexia nervosa (prevalence estimated at 0.48-0.7% among adolescents)and bulimia nervosa (estimated prevalence 3% in adolescents), little systematic research has been conducted in effective treatments for these disorders. Dr. Lock's work is beginning to remedy this through the development of systematic studies of these disorders, particularly for youth.
