I’m a Professor of Political Philosophy in the Department of Government at the London School of Economics. I work in democratic theory and the philosophy of the social sciences. Among my research interests are group decisions, social epistemology (and especially epistemic justifications of democracy), the ethics of environmental change, and the methodology of political theory and political science.
