Within the initiative "Renewing European food, agricultural and rural policies", Élise participates in the analysis of the transformation of agri-food sectors as well as changes in consumption practices. His work feeds into several prospective studies modelling the development of a sustainable agricultural system by 2050.

Before joining IDDRI, Élise worked on environmental issues related to agriculture at the international, national and local levels. Within WWF-France, her work focused on the development of a scenario for a sustainable agricultural model in France and the development of tools to measure the sustainability of the activity of agri-food companies. She has also worked at the Secretariat of the Convention on Biological Diversity (United Nations) and led a project for the Federation of the Regional Natural Parks of France which analysed agricultural and food transition initiatives in the parks.

Élise holds a Master's degree in environmental policy (with a specialisation in agriculture) from the Paris School of International Affairs (Sciences Po Paris).
