I work mostly on issues at the intersection of ethics and economics, including how we should respond to the under-consumption of vaccines and the over-consumption of antibiotics, and whether the market for biomedical enhancements should be regulated in any way. More generally, my research focuses on collective action problems.  I recently co-edited the first major anthology in Philosophy, Politics, and Economics (Oxford University Press, 2015).

I am a core faculty member in the Philosophy, Politics, & Economics program at Duke, and the faculty sponsor of the Duke PPE club.  The Duke PPE program co-sponsors the Hayek Lecture Series.
