Gastrointestinal Eosinophilic Diseases Program (GEDP) - Research

The Gastrointestinal Eosinophilic Diseases Program (GEDP) research team performs novel research focusing on eosinophils’ impact on the gastrointestinal tract. Studies center on the mechanisms that eosinophils relate to resident cells of the intestinal tract and how these relationships contribute to host health and disease.

The Gastrointestinal Eosinophilic Diseases Program (GEDP) research team is a part of the Mucosal Inflammation Program (MIP) in the Gastroenterology Division at the University of Colorado School of Medicine (CU SOM) that is directed by Dr. Sean Colgan. The MIP carries an overall theme of determining mechanisms of inflammation at a variety of mucosal surfaces including the GI tract and the lung. Taken together, the Gastrointestinal Eosinophilic Diseases Program and Mucosal Inflammation Program unite a unique blend of basic and clinical investigators. This integration of basic and clinical sciences and multidisciplinary approach fosters collaboration between key personnel from different divisions of CU SOM to provide outstanding patient care and novel research outcomes.
