Dan's research interests lie mainly in political philosophy, with an emphasis on distributive justice. His current work focuses on the foundations of social contract theory, and on the role of formal methods in theories of justice. Dan is also interested in questions about the measurement of inequality (as well as poverty), and in some theoretical issues within contemporary value theory.
Prior to joining the philosophy programme at the University of Melbourne, Dan was a graduate student at Stanford University. In between, he held brief visiting positions at UC Riverside and the Université catholique de Louvain (Belgium).
