My research is largely focused on questions about the structure of normativity, including the nature of central normative concepts like reasons, ought, and requirement, and the relationships between them. Most of my work so far has defended contrastive theories of these concepts. The basic idea of a contrastive theory of a normative concept is that whether the agent ought to or is required to perform a given action, or whether some consideration is a reason for the agent to perform the action, depends on which deliberative question, conceived of as a set of alternatives, we are asking.
A newer project is to examine the relationships between pro tanto or contributory normative concepts, like reasons, and all things considered or overall normative concepts, like ought or requirement. Some central questions here involve the idea of the weight of reasons and of competition between reasons.
