I am professor in Gastroenterology at the Department of Gastroenterology, Rouen University Hospital and associate director of the research lab INSERM ADEN UMR1073, Nutrition, Inflammation and microbiota-gut-brain axis, at Rouen Normandy University, France. My research topic is on the impact of diet on irritable bowel syndrome. Recently, I have been interested in the link between DGBI, disordered eating and eating disorders.
