Research

I study the nature of time, space, and possibility, and the relationships between things, their parts, and their qualitative properties. I also work on probability and decision theory, and I’m interested in category theory and its applications to philosophy. My work applies technical tools to traditional philosophical questions.

Teaching

I regularly teach Philosophy 450 (Intermediate Logic), which is about the limits of what can be said, proven, calculated, or counted. We study deep human discoveries about the infinite, the indescribable, and the impossible. If you've taken intro logic (or suitable courses in math, computer science, or linguistics) and you're interested in taking 450, contact me.

I also regularly teach graduate seminars and undergraduate classes in metaphysics, epistemology, philosophy of religion, philosophy of language, and philosophy of math.
