I am interested in the relationships between microbial communities and their environment, as well as the interactions of microbial populations with each other within a habitat. During my PhD (IFREMER, France) and my first post-doctorate (University of North Carolina, USA), I studied the diversity and metabolisms of microbial communities in marine subsurface habitats. Since my second post-doctorate (Friedrich-Schiller University, Germany) and my position as Professor in the Biological Sciences department at UQAM, I have been interested in terrestrial underground habitats, whether surface or deep subsurface . My other interests are aquatic habitats (surface or underground), and the microbial populations that live in the abdomen of insects.
