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 with research interests in spatial mobility, air pollution, behavioral responses, and green innovation.

Before starting the PhD, I graduated from Ecole Normale Supérieure Paris-Saclay. I hold a Master in Economics from ENSAE and Ecole Polytechnique and obtained bachelor degrees in economics, sociology and philosophy from Sorbonne University. I also worked as consultant in the Environment Directorate at the OECD.

Don’t hesitate to be in touch!
