My main research interests lie within the analytic tradition and, therein, my primary focus is on contemporary debates in metaphysics—most notably persistence, time, location relations, and time travel. Recently, I've been thinking about events and mereological simples. I'm also actively engaged in research in other areas. For instance, I've published in the philosophy of war—on Just War Theory and mercenaries, in particular. All that said, my philosophical interests are diverse and there are issues in other areas I'll explore at some stage (e.g. applied ethics, aesthetics, game theory).
