Sonia Kéfi is a researcher at the Centre National de la Recherche Scientifique (CNRS) and based at the Institut des Sciences de l’Evolution de Montpellier (ISEM), France.
She received a PhD in Environmental Sciences from Utrecht University (the Netherlands) and then spent two years at the Darmstadt Technical University (Germany) as a Humboldt fellow. She was recruited at the CNRS in 2011.
She is an ecologist interested in ecosystem complexity and how the architecture of ecological systems drives emergent properties such as stability and resilience. She combines theoretical models and data analysis from various ecosystems to address these questions. Her research aims at contributing to the fundamental understanding of stability and resilience of natural systems, but also has goals in application, and in particular, in the development of practical tools to better anticipate ecosystem responses to future environmental change.
She was awarded the Martinus van Marum prize in 2011 and the Bronze Medal of the CNRS in 2017.
