Hahrie Han is the inaugural Director of the SNF Agora Institute at Johns Hopkins University. Previously, she was the Anton Vonk Professor of Political Science at the University of California, Santa Barbara. From 2005-2015, she was an Associate Professor of Political Science at Wellesley College and a Robert Wood Johnson Health Policy Scholar at Harvard University from 2009-2011. She specializes in the study of civic and political participation, collective action, organizing, and social change, focusing particularly on the role that civic associations play in mobilizing participation in politics and building power for social and political change. Her research focuses particularly on social policy, environmental issues, and democratic revitalization.
Her most recent book, How Organizations Develop Activists: Civic Associations and Leadership in the 21st Century (Oxford University Press 2014) examines the strategies that the most effective civic associations use to engage activists and develop leaders in health and environmental politics. Another book, Groundbreakers: How Obama's 2.2 Million Volunteers Transformed Campaigning in America (co-authored with Elizabeth McKenna, Oxford Univ. Press 2014) describes the strategies the 2008 and 2012 Obama campaign used to engage so many grassroots activists in communities across America. Her first book, Moved to Action: Motivation, Participation, and Inequality in American Politics (Stanford University Press, 2009) examined the ways in which people become motivated to participate in politics, looking particularly at means of engaging underprivileged populations in political action. Hahrie’s work on participation, movement-building, civic associations, primary elections, and congressional polarization has been published in outlets including American Political Science Review, American Sociological Review, American Journal of Sociology, Perspectives on Politics, British Journal of Political Science, Legislative Studies Quarterly, Political Behavior, and elsewhere.
