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). I study how forecasts and other types of information affect actions in settings including adaptation to climate change, risk-taking in research, and time use. These days, I am especially fascinated by how people perceive and use weather forecasts—a decades-long information intervention going on every hour of the day, all around the world.
