Dr. William Stewart Agras’ research emphasizes the epidemiology and psychological mechanisms of eating disorders, while discovering and improving treatment. His research strategies included examining risk factors, studying existing treatment, and conducting longitudinal studies. Dr. Agras’ research evolved from focusing on existing or possible treatments for patients who already developed an eating disorder to researching treatments that could prevent development of eating disorders by targeting their risk factors. His consistency in theme among his past, present, and future studies reveals that Dr. Agras works towards uncovering further implications of his prior work while emphasizing new, modified treatment options for eating-disordered patients.
