Research Interests
Functional genomics on the gastrointestinal tract; probiotics. Relationship between diet, gut microbiota, and health. Linking gut microbiota, intestinal barrier, and the metabolic syndrome. How the establishment of the gut microbiota in early life may be linked to developing this condition in later life.


Research Synopsis

My research program focuses on the understanding of the molecular mechanisms regulating intestinal postnatal development. A particular focus is on the establishment of a mature mucous layer and on the role of the intestinal epithelium-gut microbiota crosstalk in this process. We are also evaluating the response of the intestinal ecosystem to probiotic bacteria.
