- 2000-2003: Engineering Master’s degree in Water and Environmental Sciences, ENGEES, Strasbourg

The extent of the impact of human activities on Earth requires to consider humankind as an environmental major force. My research interests deal with the effects of human-induced changes on the relationships between the food-web structure and the functioning of ecosystem in freshwaters. I aim at understanding how water warming drives microbial diversity and structuring and how microbial diversity and community dynamics affects microbial processes. How warming affects species trophic interactions, how species structure influences trophic interactions and ecosystem functioning and, how non-native species modify trophic interactions ?

I am working on diverse biota, from bacterial communities to fish from field survey, laboratory experiments and deterministic modeling.

Key-words: warming effect, biological invasions, stable isotope analysis, trophic interactions, microbial community structure,  denitrification activity, metabolism, phototrophic river biofilms
