My dissertation research seeks to identify systematic trends in the content of social movement issues that make them more or less attractive to the public, thus affecting the number of supporters and participants willing to join the movement. I run experiments using concepts from affect control theory and behavioral economics (such as loss aversion) to evaluate sympathy toward, and a willingness to participate in, movements that address specific types of grievances. Additionally, I am working on a research project with Kraig Beyerlein that examines mobilization and volunteer efforts to provide humanitarian aid to migrants along the United States-Mexico border.
