Claudia Sanmiguel is the Ingestive Behaviors and Obesity Program (IBOP) director at the Oppenheimer Center for Neurobiology of Stress (CNS) and she is a clinical instructor at the UCLA Digestive Diseases Division. She was born in Bogota, Colombia where she studied Medicine at the Pontificia Universidad Javeriana and specialized in Internal Medicine and Gastroenterology. Then she moved to Alberta, Canada where she did research on gastrointestinal motility and the use of artificial pacemakers and stimulators for the treatment of gastrointestinal disorders. She continued her research career at the Cleveland Clinic in Ohio and at the Cedars Sinai Medical Center in Los Angeles, where she explored the use of pacemakers and electrical stimulators for the treatment of obesity and obesity related diabetes mellitus, as well as, studied gastric electromechanical signals related to eating behavior and satiety. As part of pursuing a research career in United States, she completed her residency in Internal Medicine at Cedars-Sinai Medical Center and trained in Gastroenterology at the University of California Los Angeles. She has continued her pursue on understanding the mechanisms that regulate eating behavior in health and in obesity, and the role of the brain/gut/microbiome axis in interpreting and regulating those behaviors. She has published several papers in well known GI and bioengineering journals and presented her research results in North American and International meetings. She currently has partial NIH funding for a study on the role of brain activity and changes in eating behavior in weight loss after bariatric surgery and how some peripheral signals coming from visceral fat and gut microbiome may play a role in obesity and weight loss. She is also doing research on neuroplasticity in brain areas related to eating hehaviors in response to neuromodulation.
