Sonia Kéfi visited the INTP from July 17-24. She is a researcher in ecology at the French National Centre for Scientific Research (CNRS) in the Institut des Sciences de l’Evolution de Montpellier, associated with the University of Montpellier, and is also affiliated as an external professor with the Santa Fe Institute.
Sonia Kéfi studies ecosystem complexity and dynamics. She adresses questions related to the resilience of ecological systems to global changes using a combination of models and data analysis. She won the 2011 Martinus van Marum Prize of the Koninklijke Hollandsche Maatschappij der Wetenschappen (Royal Holland Society of Sciences and Humanities), the CNRS Bronze Medal in 2017, and the Erdős–Rényi Prize of the Network Science Society in 2020.
She visited INTP as part of a collaboration on a study on regime shifts and multi-stability in ecological networks. Her visit also provided an opportunity to discuss about the work of a PhD student staying at INTP on the effect of temperature on trophic dynamics and the role of self-regulation.
