Matthieu Sarnin graduated with a Master's degree in Political Science from Sciences Po's School of Research in 2024. Prior to that, he obtained a Bachelor's degree in Social Sciences from Sciences Po's University College. Since September 2024, he has also been working as a consultant for the Quadrant Conseil cooperative, where he participates in public policy evaluation missions for national and European administrations and local authorities. 

Matthieu Sarnin's work focuses on the steering and implementation of public policies for the ecological transition. In his master's dissertation, he examined the resurgence of the topic of energy sobriety in the formulation of a government plan during the 2022 energy crisis. His PhD thesis, undertaken as a CIFRE agreement with the Quadrant Conseil cooperative and under the joint supervision of Charlotte Halpern and Philippe Bezes, concerns the governance of the ecological transition. It does so through the study of public policy instruments developed in France to steer the ecological transition. His research aims to understand the gaps between the stated objectives, the planning processes, and the outcomes of the implementation of the ecological transition.
