Welcome to my website! I am a 5th-year PhD student in the Sustainable Development program at Columbia University’s School of International and Public Affairs.

I am an environmental economist working on climate change adaptation and with interests in spatial mobility, air pollution, and green innovation.

I am on the 2026-27 job market.

Before starting the PhD, I graduated from Ecole Normale Supérieure Paris-Saclay and worked as consultant in the Environment Directorate at the OECD. I hold a Master in Economics from ENSAE and Ecole Polytechnique. Please find my CV here.
