RESEARCH & ACADEMIC CAREER

Stephane’s research work is focusing on genomics of food-borne bacteria and on the role of microbial diversity in food microbial 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. Stephane studied fundamental & applied microbiology in Marseilles (France) and earned his PhD (1999) in molecular microbiology at the University of Amsterdam (The Netherlands). In 2016, Stephane obtained his HDR (French accreditation to steer & supervise research) in biological sciences at University Paris-Saclay.

TEACHING & ACADEMIC COORDINATION ACTIVITIES

At the Paris-Saclay University, in the framework of the BioSphera graduate school, Stephane’s is also coordinating activities to interface research & education programs and co-supervise a master degree in the field of microbiome sciences. In this context, Stéphane teaches metagenomics and molecular ecology to students having genomic and microbiology backgrounds.

From “synthetic” to defined microbial communities for clearer terminology

Jun 15, 2026

Stéphane Chaillou participated in a joint reflection with a group of international researchers, coordinated by the Austrian Institute of Technology (AIT), on the terminology used to describe certain microbial communities. The collective of experts proposes replacing the term “synthetic community” (or SynCom), sometimes perceived negatively, with “Defined Microbial Community”.
