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. More specifically, I am interested in the ways that alternatives matter in determining the normative status of our options. 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. A central part of this project is to investigate how reasons for and against various alternatives compete with one another to determine the overall normative status of those alternatives.
