My research focuses on behavior and policy preferences regarding climate change, inequality, and other societal challenges that require large-scale human cooperation. I use a variety of methods to study behavior, narrative, emotions, and underlying preferences, including incentivized/survey experiments, computational text analysis, and formal/agent-based modeling. Ultimately, my goal is to understand what motivates or demotivates individuals to act or support policies that mitigate climate change.
