I am interested in how social boundaries intertwine with political development and institutional change to affect group-based inequality. I am curious about how political communities are made and maintained, about initiatives to change political institutions, and about conflicts over the “right” allocation of rights and rewards for political membership. What and whose interests and values are at stake? How are these interests and values institutionalized? What catalyzes institutional change, and how does this change happen? I am most interested in how these phenomena affect ethnoracial group-based inequality. My research explores these questions in three broad areas: 1) structural and ideological roots of ethnic conflict and violence, 2) how social relationships channel the spread of new ideas about political community, and 3) the process of making prosocial change.
