My two main areas of interest are in contemporary post-Nietzschean political theory and philosophy and the history of political and philosophical thought. I have sought to bring these two areas of interest together by focusing on philosophical questions of difference, power, knowledge, and time, in ways that can speak to contemporary concerns without losing sight of complex contributions from the past. I have tried to draw upon ideas in contemporary thought for the purpose of staging a re-engagement with both central and marginal figures in ancient, early Christian and medieval thought, a project that culminated with my first monograph, Genealogies of Difference, published by the University of Illinois Press in 2002.  More recently I have published book chapters and articles on Deleuze's concepts of univocity and sense, Foucault on power, contemporary theories of radical democracy, and conceptions of micropolitics developed through Nietzsche, Foucault, and Deleuze. I have also now published my second monograph, Reflections on Time and Politics, with Penn State University Press.  This work develops an ontology of non-linear time in order to address issues of power, selfhood, meaning, and micropolitics.
