I'm an associate professor of philosophy at the University of Michigan, Ann Arbor.

My research has been mainly about semantics, ontology, probability, and evidence. But lately I’ve been thinking about conditions for rationality and well-being—not just for individual people, but also for groups, animals, and other cognitive systems.

I teach at the graduate and undergraduate level on a wide range of areas in philosophy. I’ve been trying to reimagine the standard philosophy curriculum to make it maximally practical, especially for students who are not philosophy majors. To this end, I created two new courses at Michigan: Critical Reasoning and Changing the World. For the former course I wrote an online critical reasoning textbook—you can check it out as a guest here. Let me know if you’d like to use it in a course!

I am also the father of four amazing kids and the husband of one amazing woman, who is a wedding florist in Ann Arbor.
