RESEARCH INTERESTSDr. Stewart has a research program that focuses on eating disorders, body image disturbance, and obesity, with a focus on the assessment, treatment, and prevention of these issues. With the dawn of new e-health technologies and population health research models to reach populations who don’t have access to or who are unable to participate in clinical programs and/or healthcare, Dr. Stewart has been a pioneer in the development and testing e-health technologies and community-based programs in order to disseminate prevention efforts to large populations for body image, eating disorders, and obesity. Dr. Stewart is an Associate Professor, the Dudley & Beverly Coates Endowed Professor, and the Director of the Behavior Technology Laboratory: Eating Disorders and Obesity, at Pennington Biomedical Research Center, and serves as Founder and CSO of Body Evolution Technologies Inc., a VC-funded entrepreneurial venture dedicated to taking e-health assessment, prevention, and treatment technologies from bench to bedside. Dr. Stewart has spearheaded unique, large, multi-site prevention and treatment studies that have included the development and deployment of novel technologies for behavior change. Her current projects include a NIH funded R01 investigating the prevention of eating disorders in female collegiate athletes across four sites, called the Female Athlete Body Program (FAB), ongoing studies examining the efficacy and dissemination of a weight management technology program, called Army H.E.A.L.T.H. for U.S. Army Soldiers, Families, and Veterans, and ongoing technology development projects, including body image and eating disorder assessment applications and eating disorder and obesity intervention platforms and applications.
