I am a sociologist and filmmaker. I investigate the social factors that determine how quickly we can mitigate and adapt to climate change. 

Climate change is a social problem – one that has been created by a certain social context and psychological outlook. I conduct research regarding how we can disrupt these systems and ways of seeing to take effective action on climate change. My research explores how and why U.S. cities act on climate change, how climate litigation can affect climate policy, and the health risks associated with climate change.  

I make films that tell the human story behind climate change as one critical approach. My award-winning fiction and documentary films include, Tribe, set in the Brazilian Amazon, and two segments of the Emmy-winning Showtime series, The Years of Living Dangerously, amongst other projects produced by my company, Evidence Based Media.

I was a Robert Wood Johnson Health & Society Scholar at the University of Pennsylvania and a AAAS Science & Technology Policy Fellow at the Environmental Protection Agency. My policy experience involves advising cities, the White House, members of Congress and the Department of State. I have written two books, and over fifty articles and book chapters. I am Associate Professor in the Environmental and Occupational Health Department in the Milken Institute School of Public Health at George Washington University and Senior Fellow at the Wharton Risk and Decision Center.
