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.
