About Me


I am an IO economist, working as Assistant Professor at Sciences Po.

My research agenda: understanding individual and firm incentives in (bidding) markets. Ultimately, to improve their organization and advance public policy.

I specialize in the structural analysis of auction/procurement data, currently working on applications in public transportation, online platforms, and the allocation of airport take-off and landing slots.
