I am interested in how social boundaries intertwine with political development and institutional change to affect group-based inequality. 

My research explores this topic 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
3) Processes and structures that promote inclusion and equity in higher education.

My current and recent work includes investigations of medieval expulsions of Jews from German cities, the early modern diffusion of new ideas about witchcraft and the incidence of witch trials, how organizational leaders build consensus and shared vision for systemic change, and the connections between ethnoreligious social structural cleavages, political mobilization, and symbolic boundaries.
