Présentation

I am an associate professor at the University of Lille, France where I have worked since 2008. My teachings concern microbiology and fermentation mainly for students of the Biological and Food Engineering department of Polytech Lille (https://www.polytech-lille.fr/english/). I belong to the BioEcoAgro research unit (UMRT 1158) that brings together about 400 researchers and technicians from INRAE, the University of Lille, the University of Liège, and the University of Picardie Jules Verne (https://www.bioecoagro.eu). My research focuses on bacterial physiology to understand how the capacity of bacteria such as growth, metabolite production and antagonistic activities are affected by environmental conditions in their habitats or in bioreactors during fermentation processes. My work concerns the bacteria Pseudomonas and Bacillus that may be beneficial for plant health because of their bioactive secondary metabolites. My team « Secondary Metabolites of Microbial Origin (MOM) » is primarily interested in bacterial lipopeptides because of their biosurfactant and their broad-spectrum antimicrobial properties.
