Axes de recherches

Mes travaux de recherche se concentrent sur plusieurs domaines clés de l’écologie : l’Écologie des communautés, l’Écologie de la pollinisation, l’Écologie du paysage, l’Écologie urbaine et la Biologie de la conservation. Mon objectif principal est d’explorer les effets des pressions anthropiques sur les pollinisateurs et les plantes, ainsi que sur les réseaux d’interactions complexes qui les lient.

Actuellement, je coordonne le projet de Liste Rouge des abeilles sauvages, une initiative visant à établir un statut de conservation UICN pour toutes les espèces d’abeilles sauvages présentes en France métropolitaine. Ce projet est crucial pour la préservation de la biodiversité et pour mieux comprendre les défis auxquels sont confrontées ces espèces.

Avec une approche appliquée, je m’efforce de rendre mes recherches accessibles et utiles à tous. Je partage ainsi mes connaissances et résultats avec les scolaires, les étudiants, les gestionnaires de territoires, et plus largement avec l’ensemble de la société, pour sensibiliser et encourager une meilleure coexistence entre l’humain et son environnement.

Research axes

My work spans several key areas of ecology: Community Ecology, Pollination Ecology, Landscape Ecology, Urban Ecology and Conservation Biology. I aim to investigate the impacts of human activities on pollinators, plants, and the intricate interaction networks that connect them.

I currently lead the French Wild Bees Red List project, an initiative dedicated to establishing IUCN conservation statuses for all wild bee species in mainland France. This project is vital for safeguarding biodiversity and addressing the growing challenges these species face.

With a strong emphasis on applied research, I am committed to making my findings accessible and impactful. I regularly engage with school groups, students, land managers, and the broader public to share insights and raise awareness. By doing so, I hope to inspire a greater understanding of and responsibility for our environment, fostering a more harmonious relationship between humans and nature.
