Welcome!
I am Professor of Economics at Nantes Université (IAE Nantes).
My research focuses on social interactions and economic behavior, with particular interest in public goods, common-pool resources, and water-related issues.
In 2023, I obtained my Habilitation to Direct Research (HDR). My HDR dissertation, Social Networks and Economic Behavior: Theory and Applications, explored how social networks shape economic decision-making and collective action.
I received my PhD in Economics in 2008 following doctoral research conducted at CIRAD. I previously studied at Toulouse School of Economics, where I completed both my Master's degree and earlier university studies.
