Research Interests

I have written on the intersections between ancient Greek natural philosophy and natural sciences, including mechanics, medicine, optics, physics and theory of mixture. Although I have written on topics ranging over the entire period of Greek antiquity, many individual research papers concern the role of Hellenistic science on natural philosophy, especially that of the Aristotelian school. This culminated in a 2009 monograph on the impact of ancient Greek mechanics on ideas about causation and explanation of the natural world.

More recently, I have been writing on the metaethical foundations of Aristotle’s ethics, especially the role of naturalism in his thought, and the recent situationist critique of virtue ethics. I am currently writing a book on Aristotle’s metaethics.

In addition, I have interests in questions of ethics and global poverty.
