I am an ecologist working at the CNRS at the Institut des Sciences de l'Evolution de Montpellier (ISEM), France. I investigate, both empirically and theoretically, how species interactions affect ecosystem functioning. I am especially interested in multi-layer ecological networks. How do the type and structure of different types of ecological interactions contribute to the stability and resilience of ecological systems?
