Short bio: I am a full professor at GATE Lyon Saint-Etienne and Saint-Etienne School of Economics. Since January 2025, I have served as deputy director of GATE Lyon Saint-Etienne, responsible for the Saint-Etienne site of the laboratory. I founded the Master's program in Political Engineering, which later evolved into the Master's program in Economics and Data for Decision Science.
My academic background includes a Master's degree in Pure Mathematics from Université Paris-Saclay and a Master's in Theoretical Economics from Université Paris 1 Panthéon-Sorbonne. I completed my doctoral thesis at Université Paris 1 Panthéon-Sorbonne, within the Centre d'Economie de la Sorbonne and the Paris School of Economics under the supervision of Michel Grabisch.
My research and teaching primarily focus on theoretical economics, particularly game theory and social choice theory. Many of my publications emphasize the axiomatic method.
I currently serve as an Associate Editor of Theory and Decision.
I have supervised two PhD students: Kevin Techer and David Lowing.
