I joined the University of Westminster in 2007; previously I worked at the University of Sheffield. I gained my PhD in 2005 from the University of Limerick.
My research interests include transitional justice, humanitarian intervention, and statebuilding in Kosovo.
My most recent book - Hollow Norms and The Responsibility to Protect (Palgrave Macmillan) – won the 2019 British International Studies Association ‘Working Group on Intervention and R2P’ book prize. I have published over fifty academic book chapters and journal articles; my work has been published in International Security, The Journal of Peace Research, Ethics and International Affairs, and Cooperation and Conflict. I have given over one hundred papers at conferences worldwide, written over fifty book reviews, and published many other academic commentaries.
I was one of the original co-convenors of the BISA Working Group on the Responsibility to Protect, and I am currently the co-editor of the Routledge "Intervention and Statebuilding" book series. I am a regular contributor to national and international television and radio.
