Dr. Stéphane Chaillou.


Stéphane Chaillou is a research director at the French National Institute for Agricultural, Food and Environmental Research (INRAe). Stéphane is a research fellow at the Micalis Institute (Food Microbiology for Human Health)  in Jouy-en-Josas, Paris area, which gathers around 90 scientists whose main objective is to develop studies on microbiology for human health and safety of food. He is stirring and supervising research projects within the Food Microbial Ecology research group (~10 people) and co-directs a Master of Science (MSc) at the BioSphera graduate school of Paris-Saclay University.

Stephane’s research work is focusing on genomics of food-borne bacteria and on the role of microbial diversity in food ecology. One of his strategy is to implement statistical and bioinformatic analysis of large sampling survey for describing diversity of food microbiomes. He is using the prediction of microbiomes fluxes along the food chain to assess food health and sustainability issues link to microbiomes such as food spoilage, biopreservation or fermentation. Recently, he has been implementing meta-omics data analysis to characterize microbial metabolic interactions in foods using synthetic ecology strategies.

At the Paris-Saclay University and within the framework of the BGE Master program (Biodiversity, Genomics and Environment) that he co-directs, Stéphane teaches metagenomics and molecular ecology to students with genomics and microbiology backgrounds.
