My core personal research focuses on theoretical issues at the individual and population levels of ecological organisation, and on the task of linking population dynamics with behavioural ecology, within the framework of evolutionary ecology. In addition to basic research, I am interested in bringing modern ecological theory to bear on significant applied problems, specifically in conservation biology. Hence, my research activities so far have focused on behaviour mechanisms underlying the Allee effect and its consequences for conservation biology. I have collaborated with many researchers at a wide range of institutions, both inside and outside France.
