His primary area of research is moral and political philosophy. He has also published in jurisprudence and philosophy of action. He explores questions in normative ethics and political theory from the perspective of practical agency embedded in a social world. This involves drawing from research in psychology, urban geography, architecture, disability studies, technology studies, literary theory, and economics. He was originally trained—in college and for his MA—in philosophy of mind and metaphysics and he continually returns to these topics in his research.
