My work focuses mostly on topics in early modern philosophy (particularly Locke, Berkeley, and Hume), ancient philosophy (particularly Plato), ethics, and law. I've authored three books: Plato's Forms in Transition (CUP 2007), Berkeley's Argument for Idealism (OUP 2013) and Locke (Wiley-Blackwell 2014); and I've co-edited two collections of articles: The Ethics of War: Essays, OUP 2017 (with Saba Bazargan-Forward) and The Ethics and Law of Omissions, OUP 2017 (with Dana Kay Nelkin).
