Research Interests:

Ph.D. UNC-Chapel Hill 2009


Hi there. I'm an Associate Professor in the Philosophy Department at University of Kentucky.

My primary research interests include the metaphysics of ordinary objects, mereology, mental fictionalism, and modality. My monograph, Parts and Wholes, was recently published with Cambridge University Press as part of their Elements in Metaphysics series (June 2023). 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” - are included in a recent volume Mental Fictionalism: Philosophical Explorations, Tamas Demeter, T. Parent, and Adam Toon (eds.), Routledge (2022), the first anthology dedicated to the topic of mental fictionalism.

Recently Taught Courses

My teaching interests continue to include a novel project of combing physical movement, performance, and the circus arts with philosophical study - a project started in 2017 with the creation of PHI 193: Circus and Philosophy. Recently, a large gym space for this class has been upgraded to accommodate multiple aerial apparatuses and circus equipment, allowing students greater room for movement and artistic exploration. This 'Circus Lab' is specifically intended to be an on-campus hub for interdisciplinary circus-centered education and research. PHI 193 will next be offered Spring 2024. 

You can learn a bit more about the class and the circus club on campus – Circus Cats – below:
