In my mediation practice, I have handled more than 600 cases involving high-value and cross-border disputes and I regularly design and deliver training programs for lawyers, judges and future mediators.
I am also a lecturer on ADR at Sciences Po and several universities.

Mediation Style

Conflict is a crisis in human interaction that destabilizes the parties making them more vulnerable. My approach aims to transform the conflict dynamics and relational interactions before focusing on problem-solving.

I work in close cooperation with lawyers and, when the case requires it, with other professionals who can contribute to finding solutions.
