My primary research interests include the metaphysics of ordinary objects, mereology, mental fictionalism, and modality.

I am currently working on a monograph (under contract) with Cambridge University Press as part of their Elements series called Parts and Wholes. It is an opinionated overview of philosophical issues involving parts and wholes, lightly guided by a diagnosis of why we shouldn’t conclude a priori that there are an odd number of things in the universe.


Two of my papers – “Mental Fictionalism” and “Mental Fictionalism: a foothold amid deflationary collapse” – recently came out in T. Demeter, T. Parent, and A. Toon (eds.), Mental Fictionalism: Philosophical Explorations (Routledge), an anthology on the topic of mental fictionalism (April 2022).
