My research focuses on late medieval and early modern philosophy. In my book, Representation and Scepticism from Aquinas to Descartes, I provide a comparative account of late medieval and early modern accounts of cognitive representation, and offer an analysis of the criticism that philosophers from both periods raised against indirect-realist theories of representation. Recently, I have been working on theories of identity and individuation in thinkers such as Pomponazzi, Hobbes, and le Grand. As a fellow of the Human Abilities Centre, I will be studying the debate on agency and causation between the English Cartesian, Antoine le Grand, and his Aristotelian critic, John Sergeant. Also, I intend to explore in more detail the account in Francisco Suárez and later Jesuit thinkers of the individuation of effects: Why does a causal power, at some given place and time, produce this effect rather than a numerically different one of the same kind?
