Margaux J. Barnes earned her B.A. in Psychology with Highest Honors from Emory University in 2007 and her Ph.D. in Clinical/Medical Psychology from the University of Alabama at Birmingham in 2014. She completed her clinical internship at the UAB-BVAMC Clinical Psychology Training Consortium in 2014, and in 2016 she completed her psychology post-doctoral fellowship in the Leadership Education in Adolescent Medicine (LEAH) program in the Department of Pediatrics, Division of Adolescent Medicine at UAB. Currently she is an Assistant Professor in the Department of Pediatrics, Division of Gastroenterology, Hepatology and Nutrition at UAB. She is currently working with the Nutrition Obesity Research Center (NORC) to evaluate a conceptual model explaining the relations between macronutrient intake, physical activity, disease status, and lean body mass in pediatric patients diagnosed with Inflammatory Bowel Disease (IBD).

As a clinical/pediatric psychologist, Dr. Barnes is interested in translational research which will inform the treatment practices for youth with IBD. Her research interests include the behavioral factors (diet, physical activity, sleep, and adherence) associated with health outcomes secondary to IBD including growth delays, metabolic health, and risk for osteopenia/osteoporosis. Dr. Barnes ultimate goal is to develop and implement behavioral interventions to promote the long-term health of pediatric patients with IBD.
