Research Interest
I am a researcher in the Eco-Evolutionary Mathematics (EEM) team of IBENS and the ENS, and also director of the interdisciplinary ENS Centre de formation sur l’environnement et la socieÌteÌ (CERES). As such, my teaching and research are spread over two main axes : (i) theoretical evolutionary ecology and (ii) interdisciplinary environment-society studies. Yet there are strong links between these two axes. In both axes, my main interest is how feedbacks between different sub-systems govern their non-linear dynamics, and foster their emergent, intrinsic dynamics and resilience to perturbations. Examples of such coupled systems in my work are : - genes-populations-dynamic landscapes ; - populations-pathogens-climate ; - biodiversity-crops-pathogens-farmers ; - abiotic resources-biodiversity-exploitation (tragedy of the commons). - socio-ecological systems including genetic evolution
