Professor Brown's fields of interest include the history of political theory, nineteenth and twentieth century Continental theory, critical theory and theories of contemporary capitalism. She is best known for intertwining the insights of Marx, Nietzsche, Weber, Freud, Frankfurt School theorists, Foucault, and contemporary Continental philosophers to critically interrogate formations of power, political identity, citizenship, and political subjectivity in contemporary liberal democracies. In recent years, her scholarship has focused on neoliberalism and the political formations to which it gives rise.
