Justin Farrell is Professor of Sociology in the Yale School of the Environment.

He studies culture, climate, and environment, with a focus on social class and epistemology. His central research question is how humans use "nature" as a moral and political category. He blends ethnographic fieldwork in rural communities with large-scale computational techniques from network science and machine learning.

His books and articles have won national awards and regularly appear in major media. He frequently presents to policymakers, including the U.S. Senate, the White House, the Vatican, and the United Nations.

His research has been published by Science, Princeton University Press, the American Sociological Review, Proceedings of the National Academy of Sciences, Nature Climate Change, Social Problems, among others, and funded by the Environmental Protection Agency and the National Science Foundation.

Justin is a proud first-generation college grad and Wyoming native.
