Megan Oser, PhD

• Director, Behavioral Medicine in Digestive Health

Dr. Oser is a licensed clinical psychologist specializing in behavioral medicine, gastroenterology/hepatology, and acceptance- and mindfulness-based behavioral therapies at the intersection of medical and behavioral health.

Dr. Oser has held leadership roles across academic medical centers and digital health technology companies. Prior to joining UCLA, Dr. Oser was faculty at Harvard Medical School and Director of the CBT and Behavioral Medicine Program at Brigham and Women’s Hospital. Her work focused on transdiagnostic CBTs for co-occurring medical and behavioral health conditions. She developed and tested novel CBTs, mindfulness-based treatments, and e-health/mobile applications, and integrated this psychological care across primary and specialty care medical settings (GI/hepatology, cardiology, transplant, neurology and infectious disease).

Within the digital health industry, Dr. Oser led clinical and scientific efforts to ensure the translation of evidence-based psychological interventions into digital therapeutics was grounded in clinical science and best practices for healthcare implementation. Her leadership within a GI-focused digital therapeutic company led to being the first to obtain FDA authorization for software-as-a-medical-device within gastroenterology.

Dr. Oser has published over 25 peer-reviewed articles, served on the editorial board of the Journal of Contextual Behavioral Science, and has provided clinical training to dozens of professionals and trainees.

Dr. Oser joined UCLA to lead the Integrative Digestive Health and Wellness Program and develop a comprehensive GI Behavioral Medicine Program. She is a faculty member in the Vatche and Tamar Manoukian Division of Digestive Diseases and serves as director of Behavioral Medicine in Digestive Health.
