I work mainly in the areas of metaphysics and action.
My current work deals with collective intentions, collective actions, the ontological status of collective agents, the epistemology of the collective, what collectives can tell us about individuals, problems concerning collective freedom and responsibility and, most recently, the collective zombie argument.
Some of my recent papers -- particularly papers with co-author, Zachary Ernst -- apply formal results from economics and game theory into problems in conceptual analysis.
