I am an economist specialized in inequality and in environmental policy. My work focuses on the measurement of economic inequality, its interactions with sustainable development and on the implementation of social and ecological policies.

I am Co-Director of the World Inequality Lab at the Paris School of Economics (PSE). From December 2022 onwards, I will be Associate Professor at Sciences Po. I am also a Senior Advisor at the European Tax Observatory and a Visiting Senior Scholar at the London School of Economics. I was recently a Visiting Scholar at the Harvard Kennedy School.
