Beth Redbird is an Assistant Professor in the Department of Sociology at Northwestern University. She is also a faculty fellow with the Institute for Policy Research and the Center for Native American and Indigenous Research. Her work focuses on how between-group boundaries impact interaction, conflict and inequality. Boundaries can be as formal as borders between nations, or as informal as cultural differences. Whether they are geographical, political, legal, or social, boundaries create inequality because limit the free flow of resources; restrict knowledge and ideas; and draw distinctions between 'us' and 'them'. Her current work focuses on two areas:(1) The ways in which modern settler-colonial boundaries constrain and influence native nations; (2) The flow of human movement within and between spaces.
