My main research interests are in philosophy of language, philosophical logic, and philosophy of mathematics. I am currently focusing on philosophical issues concerning the nature of logic and the foundations of semantics.

Before joining Birmingham in 2016, I taught at Kansas State University (2011-2016) and was a Postdoctoral Researcher at Birkbeck, University of London, and at the University of Oslo (2010-2013).


I teach modules in logic, philosophy of mathematics, and applied ethics.

Postgraduate supervision

I welcome opportunities to supervise or co-supervise research students in philosophy of language, logic, philosophy of logic, and philosophy of mathematics.

My current research focuses on philosophical issues concerning the nature of logic and the foundations of semantics. Together with Øystein Linnebo, I am writing a monograph on the logic and meaning of plurals, titled The Many and the One: A Philosophical Study (under contract with Oxford University Press). I am also working on projects about the entanglement of logic and mathematics, the role of mereology in linguistic semantics, and the paradox of Burali-Forti.
