Stephen is a political and cultural sociologist with substantive interests in Indigenous self-determination, self-government, and development, and in processes of ethnic and racial group formation. In recent years my work has focused on assertions and enactments of self-governing power by Native nations in the United States, Canada, Australia, and Aotearoa New Zealand, and on related policy issues. This work has included extensive collaborative research and consultation with Native nations, communities, and organizations in all four countries. He retired from the University of Arizona in 2018 but serves as the Faculty Chair of the university’s Native Nations Institute on a part-time basis and maintains an active research program in Indigenous government and development.
