Research

Our research group has a broad background in gastroenterology, with specific training and expertise in intestinal diseases. Nevertheless, the research includes also esophageal, gastric, liver, and pancreatic diseases, ranging from basic to clinical science.

We are interested in basically all aspects of gastrointestinal diseases, mechanisms of disease, and novel therapies, with a special attention to intestinal diseases. In particular, our group investigates mechanisms of inflammatory disorders of the gastrointestinal tract, with focus on inflammatory bowel disease (IBD). Our experimental approaches involve a combination of epidemiological investigation, clinical studies with IBD patients, in addition to molecular, cellular and animal models.

Keywords: inflammatory bowel disease; Crohn’s disease; ulcerative colitis; mucosal immunity; inflammation; carcinogenesis; epidemiology of gastrointestinal diseases.
