I specialize in ancient philosophy. My research focuses on Aristotle.

I'm particularly interested in Aristotle's metaphysical system, traditional epistemological issues including perception and skepticism, and contemporary work in category theory. I'm the author of The Foundations of Aristotle's Categorial Scheme (Marquette University Press) and Empiricism and the Problem of Metaphysics (Lexington).
