Arnaud LEFEVRE started with a Biology degree specialising in Ecological Biodiversity at the University of Versailles Saint-Quentin-en-Yvelines in 2006. He completed several research assignments in ecology and protection of natural habitats within different entities such as the natural History Museum of Paris as well as the regional nature park of the Haute Vallée de Chevreuse. He took up a master in Tool development for Sustainable Development, offered by the OVSQ in 2010, where the goal was to integrate different spheres of sustainable development, such as the environment, social, economics and politics. He tried his hand at environmental management in business through the management of low consumption buildings before returning to his preferred field, biodiversity, while working on the concept of a virtual garden of biodiversity for the Rambouillet area. Finally, he returned to the REEDS international research centre in November 2012 in the field of territorial ecology.
