My research is mostly in metaphysics and topics where it overlaps with logic, semantics, and epistemology. Lately, I have been writing about the best way to characterize different kinds of change over time. My dissertation articulates and defends a minimal A-theory. I tackle some tense logic problems left by the founder of contemporary presentism, Arthur Prior. And I argue that all change over time should be understood as a species of property change. I'm also interested in philosophy of religion.
