Rogers Brubaker is Distinguished Professor of Sociology at the University of California, Los Angeles, where he has taught since 1991. He is currently the UCLA Foundation Chair. Brubaker has written widely on social theory, immigration, citizenship, nationalism, ethnicity, race, gender, populism, and – most recently – digital hyperconnectivity. His first book explored the idea of rationality in the work of Max Weber, while his essays on Pierre Bourdieu helped introduce Bourdieu to an English-speaking audience. His next two books analyzed European nationalism in historical and comparative perspective. Citizenship and Nationhood in France and Germany (1992) sought to explain the sharply differing ways in which citizenship has been defined vis-à-vis immigrants in France and Germany and helped establish what has since become a flourishing field of citizenship studies; Nationalism Reframed: Nationhood and the National Question in the New Europe(1996) compared contemporary East European nationalisms with those of the interwar period, both emerging after the breakup of multinational states into would-be nation-states.  Subsequently, in a series of analytical essays, many of them collected in Ethnicity without Groups (2004), Brubaker critically engaged prevailing analytical stances in the study of ethnicity, race, and nationalism and sought to develop alternative analytical resources.  These informed his collaborative book Nationalist Politics and Everyday Ethnicity in a Transylvanian Town (2006), which examined the everyday workings of ethnicity in a setting of highly charged ethnonational conflict. His most recent book, Hyperconnectivity and Its Discontents (Polity, 2022) treats digital hyperconnectivity as a “total social fact.” Brubaker holds a PhD from Columbia in Sociology, an MA in Social and Political Thought from the University of Sussex (UK) and an BA from Harvard University in Social Studies.
