Steven Klein is a political theorist with research interests in democratic theory, critical social theory, theories of political economy, and the history of European social and political thought (especially of 19th- and 20th-century Germany). Thematically, his work addresses concerns such as the nature of social domination in contemporary societies and the relationship between democratic action and the institutional structure of the welfare state and capitalism. He is currently working on two book projects. The first, under contract with Cambridge University Press, examines the politics of democratic world-building in the modern welfare state. Drawing on the thought of Max Weber, Hannah Arendt, and Jürgen Habermas, the book theorizes how social movements can use welfare institutions to transform structures of domination in society. The second project draws together the thought of Karl Polanyi with the tradition of critical social theory to develop a vision of the democratic transformation of the capitalist economy. His articles have appeared or are forthcoming in Sociological Theory, the American Political Science Review, the American Journal of Political Science, and the Journal of Politics. He has held fellowships from the European University Institute, the Mellon Foundation, and the “Transformations of the State” Research Cluster at the Universität Bremen. He received his PhD from the University of Chicago.
