Primary research interests: (1) philosophy of science, (2) history of analytic philosophy, (3) categorical logic and category theory. These three themes are unified as follows: category theory and categorical logic are natural tools for the logical analysis of science — in fact, a genuine advance over the rigid syntactic methods of the logical positivists, as well as over the sloppy semantic methods of more recent years. Category theory also sheds new light on the foundations of mathematics, where I've been thinking about set-theoretic versus category-theoretic foundations, and univalent foundations, among other things.

In previous research I focused on philosophy of physics, in particular foundations of quantum field theory and quantum information theory. I hope to make further progress on those issues; but first we need to clear up some confusions about the structure of scientific theories, relationships between theories, etc. (hence the more general investigation described in the previous paragraph). I also dabble in experimental metaphysics, and make the occasional foray into science-religion issues, e.g. cosmology and theology, the fine-tuning design argument, and methodological naturalism.
