Glycobiology of host-microbe interactions in the gut


I have led a Research Team, since 2008, that investigates the glycobiology of host-microbe interactions in the gut.

My previous research focused on the structure-function relationships of plant and microbial glycoenzymes and their potential biotechnological application (stemming from my PhD project on barley amylases in Biochemistry-Molecular Biology of Nutrition, Marseille University, France in 1993) and successive postdoctoral positions on fungal glucoamylases at the Carlsberg Research Institute (EMBO and EU-funding) and Institute of Food Research (Marie-Curie fellowship).

After obtaining a lectureship position in Marseille University in Biochemistry and Molecular Biology (in 1997), I led a research Group on Glycosidases in Marseille (1997-1999) and in Norwich (1999-2004) while on secondment at IFR. I put together and coordinated an EU FP5 project on glycosidases and glycosidase inhibitors in food processing (1999-2003),.I obtained a post-doctoral qualification “Habilitation à Diriger les Recherches” in Marseille back in 2005.

Today my team studies the molecular mechanisms of gut bacteria/mucin interactions in health and disease.
