Our research group is working on the mechanisms of tumor development in the gastrointestinal tract, especially during chronic inflammation elicited by Helicobacter pylori infection in the stomach. Another focus is the deregulation of the Wnt signaling pathway during bacterial infection in the intestine and colon. In parallel, we are interested in identifying targets to develop novel prophylactic approaches and therapeutic strategies for H. pylori infection and stomach cancer.
