My core interests are how individuals react to collective problems such as climate change, focusing on individual behaviors and support for public policies. Human flourishing depends on continuously reconciling short- vs. long-term motivations and individual vs. collective interests. I build models predicting social and political behavior from cognitions, individual differences, and social context. I am also interested in communication effectiveness, both for supporting informed decisions (i.e., communicating harms and benefits) and for behavior change (persuasion). My upcoming research will primarily investigate the social psychological underpinnings of behaviors that advance or obstruct the public interest. I have been supported by the US National Science Foundation and two other fellowships, and hold a university teaching award.
