Primary fields of research

Current research focuses on improvement of diagnosis and pharmacological management of diseases in internal medicine - in particular inflammatory bowel disease. In collaboration with national (the Biotech Research and Innovation Centre, University of Copenhagen and University of Southern Denmark) and international research teams (Boston, Houston, Redwood City/Stanford, Singapore, Ottawa/Toronto, and Zürich) the importance of the intestinal barrier function for maintenance of homeostasis / development of inflammation is investigated, including the impact of intestinal epithelial cells. Further, the multifactorial interplay of gene-environment interaction (genetics and epigenetics as well as environmental factors, including luminal antigens) in the etiopathogenesis of inflammatory bowel disease is a mainstay of interest-based activity.

Fields of interest

Cellular and molecular mechanisms of inflammation pertinent to clinical and pharmacological improvement of patients with disorders related to internal medicine - with particular spotlight on inflammatory bowel disease.

Safeguarding the undergraduate clinical training of medical students in the fields of internal medicine / medical gastroenterology.
