I am currently working on two main lines of research, one in political philosophy, and the other in ethics and moral psychology.
In political philosophy, I am interested in how our thinking about what states owe to their own citizens and what they owe to non-citizens should fit together. My dissertation was on the nature and significance of what I call “external relationships.” These are relationships that extend beyond the borders of a given society, such as a marital relationship between a citizen and a non-citizen. External relationships, I hold, give rise to difficult and interesting issues because the very same policies may affect both the citizens and non-citizens who are in them. Some of my research attempts to demonstrate that external relationships have important implications for recent debates in the ethics of immigration literature.
In ethics and moral psychology, my research is driven by a strong interest in the relationship between empirical facts and normative principles. I hold that philosophers have an important role to play in empirical research on moral topics, and that traditional philosophical and empirical methods can be brought together to illuminate issues in ethics. More specifically, I have been studying the nature of moral judgment and the psychological bases of moral categorization. In some of this work, I have been looking at whether certain ways of conceptualizing important moral problems, such as severe poverty in developing countries and anthropogenic climate change, are more effective in inspiring moral concern and action than others. With Peter Singer, Paul Slovic, Daniel Västfjäll, and Joshua Greene, I recently received a grant from the Princeton University Center for Human Values to conduct research on the role that philosophical arguments can play in promoting prosocial attitudes and behaviors.
Bringing these two lines of research together, I am working with Nicholas Southwood on the Australian Research Council Future Fellowship “Feasibility in Politics: Taking Account of Groups and Institutions.” This research examines how feasibility considerations should impact our moral theorizing about three main practical issues: immigration, poverty, and climate change. We are using traditional philosophical and empirical methods to better understand how considerations of feasibility bear on the evaluation of groups and institutions addressing each of these issues, as well as the role that feasibility judgments should play in politics more broadly.
I am also working on a number of other research projects, and am always glad to find new collaborators to work with.
