I am an Associate Professor in the Sociology at the University of North Carolina, Chapel Hill. My current research is on contemporary US social movements and the uses of media data for understanding movement processes. With Edwin Amenta, I am the author of Rough Draft of History: A Century of US Social Movements in the News (Princeton 2022). My work has also appeared in journals such as American Sociological Review, Social Forces, Social Problems, and the Annual Review of Sociology.

I currently serve as the editor of the interdisciplinary social movements journal Mobilization, the premier journal of research specializing in social movements, protests, insurgencies, revolutions, and other forms of contentious politics.
