Sean Gray is a Postdoctoral Research Fellow at the Ash Center for Democratic Governance and Innovation, Harvard University. His research and teaching interests are in democratic theory, critical social theory, and deliberation and public engagement. He also has interests in applied ethics and the history of political thought. His current book project, Democracy and Silence, theorizes how silence can be a form of political engagement and links communicative uses of silence in politics to changing patterns of participation and nonparticipation across the developed democracies. Gray was previously a Graduate Fellow at the Edmond J. Safra Center for Ethics, Harvard University, where he studied as a Fulbright Scholar. He holds a PhD in Political Science from the University of British Columbia (2016) and a B.A. (Hons.) from Queen’s University, Canada. At Harvard, Gray teaches a graduate-level course in ethics and public policy at the Kennedy School, and an introductory course in contemporary democratic theory.
