About

After spending several years structuring and improving Waste-to-Energy plants energy efficiency at SUEZ R&R France, I want to broaden my knowledge about energy production plants. As Performance Manager for the Île-de-France Grand Est & Bourgogne-Franche-Comté area, I help EfW plants increasing their overall performance and developing new businesses, from a technical, operational, and economic perspective. Former graduate from Ecole Polytechnique and Imperial College London, I specialised in Urban energy systems, Energy systems analysis and Energy technologies. I have a firm belief in the Energy Transition and experience within the Energy Industry.
