Welcome to my website!

I’m a third year Ph.D. candidate in Economics at the Paris School of Economics and Université Paris 1 Panthéon - Sorbonne, advised by Katheline Schubert.

My research focuses on environmental macroeconomics, with an emphasis on the study of the impacts of climate policies. I build heterogeneous agent models to study the drivers of climate policy acceptability.

News:

• I am the co-recipient, with Paloma Péligry, of the 2025 FAERE Best Young Economist Paper Award for our paper Climate Policies in the Housing Market.
• In the Spring 2025, I visited the Institute for International Economic Studies (IIES) in Stockholm, hosted by John Hassler.

Prior to my doctoral studies, I have been research assistant in multiple french institutions, and worked on an interdisciplinary project to assess the macroeconomic impacts of climate change in Viet Nam.

I hold a Masters in Economics (APE) from the Paris School of Economics, a B.Sc and Magistère in economics from Université Paris 1 Panthéon Sorbonne.
