I a senior scholar of philosophy at The Salem Center, at the University of Texas, Austin.  I've previously held teaching and research positions at Rutgers University, Boston University and the The University of North Carolina, Chapel Hill.

I specialize in ancient philosophy (especially Aristotle), epistemology (especially the relevance of theories of concepts to issues of justification), ethics (especially topics pertaining to the objectivity of values, the moral status of productive work, and the relation between morality and self-interest), and political philosophy (especially topics pertaining to individual rights and the moral foundations of capitalism).
