About me

I am an Assistant Professor at Université Paris Dauphine (France), where I specialize in computational social choice, with a focus on matching and fair division. My research explores how mathematical and algorithmic tools can address challenges in collective decision-making and resource allocation.

During my PhD at Sorbonne Université (formerly Université Pierre et Marie Curie), supervised by Patrice Perny, I studied linear programming formulations for combinatorial optimization problems involving non-affine aggregating functions, such as the ordered weighted average (OWA) and the Choquet integral.

For more details check my PhD thesis.
