I am an environmental economist at Columbia University's School of International and Public Affairs (SIPA). I am affiliated with CEEP, the Climate School, and the Institute for the Study of Labor (IZA). From 2023 to 2024, I was a Senior Advisor in the Office of Information and Regulatory Affairs (OIRA).
