Primary fields of research

Current research focuses on improved diagnosis and pharmacological management of diseases in internal medicine - in particular inflammatory bowel disease. In collaboration with national (Biotech Research and Innovation Centre and University of Southern Denmark) and international research groups (Boston, Houston, Palo Alto, Singapore and Zürich) the importance of the intestinal barrier for maintenance of homeostasis / development of inflammation is investigated, including the relevance of intestinal stem 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 main topic of interest.
