My work focuses on global inequality and environmental policy.

I am a tenured Associate Professor of Economics at Sciences Po where I’m affiliated with the Center for Research on Social Inequalities and the Department of Economics. I am also Co-Director of the World Inequality Lab at the Paris School of Economics and Senior advisor at the European Tax Observatory.

In 2023-2024, I am a visiting Associate Professor at the Harvard Kennedy School.
