My research focuses on the understanding of the functioning of microbial communities. I address this question by organizing my work around the following two themes:
1/ Diversity and functioning of biofilms and microbial mats: mainly in aquatic ecosystems (freshwater and marine). I am mainly interested in coastal ecosystems with a clear preference for the tidal zone. I study the diversity of microorganisms in these biofilms and their role in the functioning of ecosystems.
2/ Interactions in microbial ecosystems: between microorganisms (communication, ...) or between a host and a microorganism (symbiosis, ...)
I teach mainly in ecology and statistics (univariate and multivariate) at the Museum of Natural History and other institutions/universities. I am responsible for the optional module TC3-ini: Introduction to Statistics and Probability (http://plateforme-depf.mnhn.fr/course/view.php?id=57).
I perform experiments for outreach purposes. Below is an experiment to document the changes observed in a Winogradsky column. The high resolution version of this poster is available for download at the following address: 
I am in charge of the meiofauna (http://www.mnhn.fr/fr/collections/ensembles-collections/invertebres-marins/meiofaune) and siponcle collections.
The meiofauna collection gathers nearly 800 different species (and as many types) on slides, corresponding to more than 3000 microscopic preparations, the inventory of which is computerized with JACIM. This collection includes 8 different phyla (Annelida, Gastrotricha, Kinorhyncha, Loricifera, Nematoda, Platyhelminthes, Rotifera, Tardigrada) and is accompanied by an important library on various groups living in the interstitial environment.
