Fiona's main area of research concerns Plato's metaphysics and in particular his later period dialogue, the Sophist. She is currently working on a monograph that offers a novel reading of Plato's Sophist. This reading argues that the dialogue's central question is what it is to give an account (logos) of something in the world, and contains an account of being according to which there are two modes of being, constituting the nature of some property and conforming to such a nature. It is also claimed that cases of the first mode (Forms) are causes of cases of the second mode, and it is suggested that Forms are not universals.
