Dr. Jill Gaidos is an Associate Professor of Medicine, Vice Chief of Clinical Research in the section of Digestive Diseases and the Medical Director for the Yale Inflammatory Bowel Disease (IBD) Program. Dr. Gaidos completed her medical school, internal medicine internship and residency training at the Virginia Commonwealth University (VCU) in Richmond, Virginia. She completed her Gastroenterology Fellowship Training and the Advanced Postgraduate Program in Clinical Investigation at the University of Florida in Gainesville. She then returned to VCU where she was on faculty for 9 years prior to moving to Yale. While at VCU, she was Director of IBD, Director of GI Clinics, and Deputy Chief of Gastroenterology and Hepatology at the Richmond VA Medical Center. While in Richmond, she established a national program to provide comprehensive IBD care to veterans around the country. She is also well known nationally through her work with the Crohn's and Colitis Foundation and with the American College of Gastroenterology, chairing educational meetings and lecturing throughout the country on IBD. She has tremendous experience in IBD clinical research, running more than a dozen clinical trials in IBD at once. Dr. Gaidos sees patients with inflammatory bowel disease (including Crohn's disease, ulcerative colitis and microscopic colitis). She is always happy to see complex patients with a long history of IBD, those who have been treated with multiple medications, patients with difficult to manage IBD, and patients with concerns about pregnancy and IBD. Dr. Gaidos is involved in industry-sponsored and investigator-initiated research focusing on the treatment of ulcerative colitis and Crohn's disease at Yale.
