I am investigating the ecology of microbial communities, with a particular interest in those involved in the cycling of nitrogen in agricultural soils.

Presentation

My main research interest lies in the understanding of the structure and the functioning of natural microbial communities. After completing a PhD mainly focusing on communities associated to diverse microbial mats, I decided to give to my research an applied perspective by investigating the ecology of soil microbial communities in agro-ecosystems. My current projects involve both field and experimental work, with an emphasis on the assessment of the role of community composition (both above and belowground) on the genetic potential for different N transformations (nitrification, denitrification and DNRA) in arable soils (including bulk soil, rhizosphere and root compartments).
