My research activity focuses on vegetation reconstruction, climate quantification and on the estimation of Cenozoic paleo-elevations from pollen data. In particular, my work enables a better understanding of the conditions for the establishment and evolution of plant diversity around the Mediterranean and in Europe since the beginning of the Cenozoic thanks to a better knowledge of the respective influence of climate change, CO2 levels, tectonics and anthropic impact on vegetation. The specificity of my research work is to be inter-disciplinary, working at the interface of earth and life sciences. By quantifying environmental parameters, I make the link between palaeontologists, ecologists, geologists and climate modellers.
