I am currently Professor at Institut Pasteur, head of the Genetics of Biofilms Unit in the Department of Microbiology. I was trained as a high-school biology teacher, but I got sidetracked and, instead, I started research as a undergraduate student in 1990 with Cécile Wandersman ( In memoriam) at the Institut Pasteur, Paris, France (type 1 protein secretion and haem acquisition in Gram-negative bacteria). I then obtained my PhD in 1994. After being appointed Research Assistant at the Institut Pasteur in 1995, I took a post-doctoral leave of absence in 1996 to join the laboratory of Jon Beckwith at Harvard Medical School, Boston, USA, (cell division in Escherichia coli). I went back to the Institut Pasteur in 1999 to develop an independent project investigating bacterial biofilms. This led to the creation of the Genetics of Biofilms 5 year young investigator group (G5) in 2002, which was turned into a full Research Unit in 2007.
Extracellular polysaccharides are important determinants for bacterial biofilm formation that are secreted by ill-characterized synthase-dependent systems. Scientists from the Institut Pasteur and CNRS reveal that Escherichia coli secretes cellulose by a conserved multicomponent membrane-embedded […]
