I have wide interests in the field of political theory. Although in the past I have done some work in the history of political thought, my research is now focussed on issues in contemporary political theory and philosophy. These include: theories of justice and equality; democratic theory; the concepts of nationality and citizenship; multiculturalism and immigration; and global justice. My book National Responsibility and Global Justice was published in November 2007, and I am continuing to work on questions that arise from that book, in particular the relationship between social justice and global justice, and the question of how the boundaries of distributive justice are set. I have also been working on the issue of territorial rights, and the principles that can be used to settle territorial disputes - I have published three papers on this topic. Most recently I have worked on immigration, in a series of articles culminating in my 2016 book Strangers in our Midst: the political philosophy of immigration. I plan to continue working on these topics in future, as well as writing a short book on political self-determination.
Current Research Projects
The social significance of national identity; selecting refugees; self-determination and territory; need-based justice.
