I am a Professor of Politics at the University of Manchester.
I am currently working on two projects. The first (with Luke Glanville at ANU) considers the ethics of global prioritisation. Although states have global responsibilities across several issue areas, they also have significant budgetary and resource limitations in what they can do to tackle all the various ongoing and potential crises worldwide. Tackling one crisis, and fulfilling one set of responsibilities, typically raises opportunity costs for other crises and for fulfilling global responsibilities elsewhere. In the face of budgetary and resource limitations, states have to decide which global responsibilities they will focus on. If states cannot fulfill all their global responsibilities, such as to tackle mass atrocities, global poverty, disease, and climate change, which should they prioritise?
The second considers how global responsibilities may shift in a post-liberal international order. It considers, for instance, changes to the responsibility to protect and the principles of just war theory, in light of a much more challenging international environment. From Jan 2023, I will have a Mid-Career Fellowship from the British Academy to work on this project.
More generally, my work focuses on ethical issues in international politics. I have particular research expertise on humanitarian intervention and the responsibility to protect (R2P), Just War Theory, private security, and the alternatives to war (e.g. sanctions).
I have written three books (all with Oxford University Press) and over 30 journal articles since 2007, including in British Journal of Political Science, Ethics & International Affairs, European Journal of International Relations, International Studies Quarterly, Journal of Political Philosophy, and Review of International Studies.
My most recent book examines the ethics of the alternatives to war (The Alternatives to War: From Sanctions to Nonviolence, Oxford University Press, 2018). An interview with me about the book for the Carnegie Council is here. I have also put together a module guide for teaching the alternatives to war.
My second book considers the ethical challenges posed by the rise of private military and security companies (The Morality of Private War: The Challenges of Private Military and Security Companies, Oxford University Press, 2014).
My first book explores the ethics of humanitarian intervention and the responsibility to protect, focusing on the question of who should intervene (Humanitarian Intervention and the Responsibility to Protect: Who Should Intervene?, Oxford University Press, 2010)
I also currently co-edit a book series on War, Conflict, and Ethics for Routledge. Please feel free to contact me with book ideas.
I gained my PhD from Newcastle University in 2006. From 2007-2009, I was a Senior Lecturer in International Relations at the University of the West of England, Bristol. I joined Manchester in 2009 and was promoted to full professor in 2014. I have served as the Director of Research and the Politics REF coordinator for the 2021 REF, where we climbed to 8th (from 19th). I currently serve on the University Senate. I also serve on the Governing Council of the ISA and co-convene the International Political Theory section of the ECPR.
I am willing and keen to supervise PhD students in my areas of interest.
