Activités de Recherche

The research theme of my group is to understand the ecology of soil microbial communities, especially those involved in nitrogen cycling. We mostly focus on denitrification, which is a microbial respiratory process consisting in the reduction of soluble nitrogen forms, nitrate and nitrite, into gas, nitric oxide, nitrous oxide and dinitrogen when oxygen is limited. Denitrification is the main biological process responsible for the return of fixed nitrogen to the atmosphere, thus completing the N-cycle. It is also responsible together with nitrification for the loss of nitrogen, an essential plant nutrient and for the emission of N2O, an important greenhouse gas.

We are currently using N-cycling as model traits for bridging microbial community ecology, microbial processes and ecosystem functioning. For this purpose, both temporal and spatial patterns of microbial community activity, diversity and abundance are investigated.
