At the global scale, aquatic ecosystems play major roles in climate regulation and carbon fluxes. Deciphering the processes involved in the functioning of these ecosystems and in the biogeochemical fluxes is essential to grasp their temporal dynamics and how they are affected by disturbances such as those produced by global changes. Microbial communities are extremely complex in most environments, because of their diversity that is characterised by various metabolism, the numerous interactions they can sustain with other organisms in their environment, the life cycles composed of diverse development stages, the capacity of most microorganisms to enter into stages of low cellular activity when environmental conditions become unfavourable as well as their capacity to migrate and to colonise new environments. It is supposed that these features could allow microbial communities to be resilient when facing changing environmental conditions, either intra-annual variations (e.g. seasons) or inter-annual (e.g. global changes), and thus to maintain ecosystem functioning. It is usually assumed that the organisms at the top of trophic webs are more sensitive to changes in their environment. However, because microorganisms are at the bottom of trophic webs, any shift, even trifling, at the level of this community could impact and destabilise in cascade the functioning of the ecosystems. The aim of my research activities is to better appreciate microbial diversity, to understand the processes that structure this diversity and to identify the role played by microorganisms in the functioning of aquatic ecosystems.

MAIN AND CURRENT SCIENTIFIC ADMINISTRATIVE RESPONSIBILITIES
*CURRENT TEACHING ACTIVITIES
My teaching focuses on ecology and, in particular, on the ecology of both marine and freshwater aquatic environments. More precisely, I develop the different fields of microbial ecology, namely the study of microbial diversity, the factors (biotic and abiotic) determining the temporal dynamics and spatial distribution of microorganisms and the role of microbial communities in the functioning of ecosystems.
I am mainly involved in the Bachelor's Degree in Organism Biology and Ecology (BOE) and the Professional Degree in Urban Plant Landscapes (ECOPUR) and in the Master's Degree in Biodiversity, Ecology and Evolution (BEE). My teaching is divided between practical and supervised work, field training and lectures.
