At the frontier between applied and fundamental research, my work focuses on ecosystems functioning and biodiversity patterns in spatially heterogeneous environment.
After a PhD project on the impact of river restoration on soil fauna communities, their interactions and their relations to ecosystem functioning, I integrated the Evolution and Community Ecology team for a post-doctoral project. My current work aims at acquiring a mechanistic understanding of the impact of spatial heterogeneity on species coexistence and ecosystem functioning. I use both mathematical models and field data to disentangle this question and produce guidelines for ecosystem management and restoration.
