RESEARCH: Microbial Interactions - Biofilms - Environment
Biofilms, Environnemental Microbiology, Microbial Biodiversity, Interactions and cell to cell communication, Chemical Ecology, Quorum-sensing, Quorum quenching, Antifouling, Bioactive compounds.

Biofilms are complex microbial associations found in a wide variety of environments. They colonize natural or artificial surfaces and are essential for the functioning of ecosystems or organisms. But these structures can be harmful in many contexts: they are the reservoirs of many pathogenic bacteria, they constitute favorable environments for the acquisition of antimicrobial resistance, they present a capacity of pipelines obstruction by growth, ...

The main goal of my research projects is to better understand the cellular and molecular mechanisms leading to the establishment of these biofilms. In particular, my research focuses on inter-cellular interactions in these structures (quorum sensing, quorum quenching). The long-term challenge is the identification of new and effective antifouling compounds that respect the environment.
