My primary area of interest is evolutionary game theory and the
naturalistic study of social norms. I am currently working on
evolution of social norms in finite population settings as well as the
evolution of indirect reciprocity. I have also done work on the
evolution of cooperation in spatial settings. Outside of this
area, I have interests in the philosophy of science, philosophy of
biology, philosophy of logic, and the modern empiricists (especially
Hume).
