I specialize in moral and political philosophy, moral psychology, and experimental philosophy. My work is animated by an interest in the role that empirical facts should play in the evaluation of normative concepts. I argue that moral and political philosophers should be (and have often been, explicitly or implicitly) interested in the fruitfulness of these concepts – how well they help us to solve practical problems. This argument provides a novel defense of the positive program in experimental philosophy. I am also interested in how political philosophy should take facts about the real world into account. In particular, the fact that citizens and non-citizens of democratic states stand in relationships with one another generates stringent duties to implement more open immigration policies. I hold that philosophers have an important role to play in empirical research on moral and political issues, and that traditional and empirical methods can be brought together to illuminate these issues.
