Presentation

My main research interests lie in the area of the evolutionary ecology of predators. Within this field, I mainly work on the evolution of life-history strategies, in particular reproductive strategies, and chemical ecology. The organisms I’m interested in are ladybirds (Coccinellidae: Coleoptera), mainly those predating on aphids (Aphididae) and coccids (Coccoidea). In this context, I have acquired a large experience on the natural history of Coccinellidae, both in the field and the lab, and good knowledge on their systematics and phylogeny. I have currently two main research projects: the evolution of asexuality, and the evolution of colour. Subsidiarily, I have applied projects in the field of biological control of agricultural pests. In the first years of my associate professor career (2000-2006) I was faced with a new field – teachers training in ecology (French agricultural secondary school system). The objective of the ecology national curriculum, following European regulations favouring sustainable agriculture, was to give pupils (future agricultural professionals) a better understanding of the environmental framework within which they would be working and a better appreciation of environmental questions. Although well intentioned, the curriculum was difficult to teach: teachers felted unable to link ecology concepts to the applied agricultural matters pupils were interested in and to motivate them. Therefore, I developed research projects on ecological education. Today, although my research activities are focused on ecology, I still devote time to a partnership with secondary school teachers to produce teaching resources for ecology education, often based on my own research projects in ecology. I believe this collaboration between research in ecology and ecology education, is essential to foster the adoption of agroecology practices by farmers, teachers and pupils
