I am currently writing a book on the nature of universals, to be published by OUP. I recently published another monograph on the metaphysical origins of analytic philosophy (On the Genealogy of Universals: The Metaphysical Origins of Analytic Philosophy, 2018). I am also working on the history of late analytic philosophy..
More generally, my published work covers four interrelated fields.
(1) Metaphysics: Meta-Ontology, Truth-Making, Essentialism, Relations, Universals
(2) Philosophy of Mathematics: Neo-Freganism, Structuralism, Fictionalism
(3) Philosophy of Language: Reference, Predication and Quantification
(4) History of Analytic Philosophy: Frege, W.E. Johnson, McTaggart, G.E. Moore, Ramsey, Russell, Stout, Whitehead, Wittgenstein (early 20th century) and Quine, Davidson and Lewis (late 20th century)
