I am interested in ancient ethics and moral psychology generally, but especially as they relate to questions about the objectivity of norms and value. My main interest is in Plato, but I have taken a long detour through Stoic (i.e. Socratic) ethics and moral psychology.

I have recently co-edited The Oxford Handbook of Hellenistic Philosophy with Nathan Powers (SUNY Albany). I am currently completing a book manuscript on The Ethics of the Older Stoics, and Nate and I are writing a book on The Stoics for Routledge's Great Philosophers series. I plan to return to Plato on the other side of these projects.
