Welcome!
I am currently a Professor of Economics at Nantes Université (IAE Nantes). I obtained my Habilitation to Direct Research (HDR) in 2023. My HDR dissertation, Social Networks and Economic Behavior: Theory and Applications, focused on the role of social interactions in economic decision-making, with applications to public goods and common-pool resources, particularly water-related issues.
The HDR committee included Nizar Allouch, Frédéric Deroïan, Jean-Christophe Péreau, Benoît Sévi, Thomas Vallée, and Yves Zenou.
I received my PhD in Economics in 2008, with my doctoral research conducted at CIRAD. I hold a Master's degree from Toulouse School of Economics, where I completed all my post-baccalaureate studies.
