I study and teach about the politics of self-determination. This work engages with several thematically defined fields: nationalism and ethnic politics, peace and conflict studies, and settler colonialism and indigenous politics. In short, I try to understand how nationally and ethnically identifying collectives contest the meanings, practices, and institutions of self-determination. I am particularly concerned with questions about decolonization, democracy, and justice in places with histories of colonization, territorial dispossession, and the movement of human populations.
