Heaney researches the interaction of political parties, social movements, interest groups, and social networks from an interdisciplinary perspective. His research has examined the politics of health and welfare lobbying, the grassroots politics of the antiwar movement after 9/11, and social networks among activists in the Democratic and Republican parties. His current agenda focuses on organizational and grassroots mobilization in the aftermath of the 2016 election, including the resurgence of women's activism, as well as other emerging protests on the right and left of the political spectrum.
Examines how partisanship and social networks affect the willingness of interest groups to contribute to collective advocacy in conjunction with other organizations.
Addresses how organizations that mobilize women as women, in an era when other women’s groups struggled to maintain critical mass, fostered collective consciousness among women, a large and diverse group, while confronting the echoes of backlash against previous mobilization efforts by women. Argues that groups like the Million Mom March and Code Pink: Women for Peace achieved mobilization success by creating hybrid organizations that blended elements of three major collective action frames: maternalism, egalitarianism, and feminine expression.
Demonstrates that co-membership networks of national party convention delegates are highly polarized by party, even after controlling for homophily due to ideology, sex/gender, race/ethnicity, age, educational attainment, income, and religious participation. Argues that segregation of organizational ties on the basis of party adds to the difficulty of finding common political ground between the parties.
Analyzes intermovement dependency by illuminating how hybrid organizations are a vital part of the mobilization process for peace.
Examines post-9/11 social movements and how they compare and contrast to those of the 1960s, specifically the role of partisan polarization in the prior.
Illuminates stories of ordinary people who tried to stop and end the U.S. wars in Iraq and Afghanistan, shows that activists come from many different walks of life, and explores a variety of modes of activism in addition to marches.
