Research interest:

The research of our group, integrated in the IRIB Institute, are mainly dedicated to the study of eating disorders, irritable bowel syndrome (IBS) and inflammatory bowel diseases (IBD). These pathologies share common features of intestinal inflammation and dysregulation of the gut-brain axis and offer great opportunities for innovative therapeutic strategies (immunonutrition, neurostimulation). Our projects explore the underlying mechanisms of these diseases from the molecular level to clinical trials. This broad range of research from the bench to the bedside is the result of our research strategy that brings together basic and clinical sciences, in a tight collaboration between laboratory scientists and health professionals. Our dynamic research team has an active research strategy which also drives the translation of research from the laboratory to patenting and creation of biotech company entrepreneurship (TargEdys).
