As an agronomist and microbiologist, I am passionate about the links between bacteria and food. Milk and egg are consumed all over the world and take an important part in our daily protein and lipid intake. Bacteria are sometimes responsible for alterations in milk and egg. On the contrary, for milk, they can, through fermentation, multiply the milk benefits in the fields of nutrition, health and gastronomy.

Beyond the scientific rigor, which is inseparable from any scientific approach, curiosity and passion have driven and still drive in my daily professional life. Microbiology, an experimental discipline par excellence, allows to address thousands of questions and to satisfy the most insatiable curiosities. Combined with these two foodstuffs, milk and egg, it gives me a playground as well as a fount of wonder, from my very first training periods until today.

After graduating from ENSA Rennes (Agronomist, 1992) and from the University of Paris XI-Orsay (PhD in Microbiology, 1996), my research has always focused on bacteria for dairy production and processing. When I was recruited at INRA (Jouy en Josas) in 1997, I studied Lactococcus lactis, one of the main lactic acid bacteria, and its abilities in DNA transfer, protein secretion and respiration. When I moved to Rennes in 2001, I initiated research works on Staphylococcus aureus, an opportunistic pathogen of the dairy production chain: adaptation to the ruminant host and interactions with lactic acid bacteria. From 2008 to 2016, I headed a research team (12 permanent staff including 7 scientists), whose works dealt with S. aureus but also with Propionibacterium freudenreichii, a dairy propionic acid bacterium. Since January 2017, I am Director of the UMR STLO and pursue my research activity within the MicroBio team.

As a scientist, I have published about 100 articles and book chapters, and coordinated research projects on lactic acid bacteria and Staphylococcus aureus, with regard to the dairy production chain.

As Director of the UMR STLO, I am now at the service of a robust, dynamic and creative collective, whose works deal with all their facets of milk and egg. This leadership function, although a bit less scientific, is challenging and stimulating and I assume it with the curiosity and passion that have driven my scientific career.
