I am an associate professor in the Department of Philosophy at Ohio State University  
At the broadest level, my research focuses on four philosophical questions about ethics:
  • Is there a correct theory that tells us which actions are right and wrong, and helps to explain why?
  • If so, what is the structure of that theory?
  • How do our ethical commitments and practices fit into our broader conception of how the world works?
  • What is the best way of going about answering the preceding questions?

If you have a fetish for CVs, mine can be found here.

I hail from Vancouver, Canada, which has left me with weaknesses for 
vegan cuisine, karaoke,  and the martial art aikido (although the latter interests have been sadly neglected in  recent years). I live in Columbus, Ohio with my love Amy Shuster, and our son Finn

If you are here because my Facebook and google+ pages are shockingly cryptic, you can learn more about me here.

What I am up to (Spring 2017):

This Spring I am eagerly anticipating the proofs for
The Routledge Handbook of Metaethics (co-edited with David Plunkett), helping to shepherd the volume Philosophy and Climate Change (co edited with Mark Budolfson and David Plunkett) towards completion, and working on papers on metaethical implications of the idea that we should be steadfast in the face of certain moral disagreements (with Jamie Fritz), on detaching pure expressivism from minimalist theories, and about the significance of conceptual ethics for normative theorizing (with David Plunkett). I am excited to be teaching the Gateway Seminar this semester, which introduces new philosophy majors to the craft of philosophy.
