My research deals with the theory and history of international law, particularly in the areas of the use of force, humanitarian law, human rights and migration.
Recent significant publication is Targeted Killing: A Legal and Political History (Cambridge University Press, 2016). Looking beyond the events of the second Intifada and 9/11, this book reveals how targeted killing is intimately embedded in both Israeli and United States statecraft and in the problematic relationship between sovereign authority and lawful violence underpinning the modern state system. It details the legal and political issues raised in targeted killing as it has emerged in practice, including questions of domestic constitutional authority, the norms on the use of force in international law, the law of belligerent occupation, the law of targeting and human rights. The distinctive nature of Israeli and United States targeted killing is analysed in terms of the compulsion of legality characteristic of liberal democracies, a compulsion that demands the ability to distinguish between legal ‘targeted killing’ and extra-legal ‘political assassination’. The effect is a highly legalized framework for the extraterritorial killing of designated terrorists that may significantly affect the international law of force.
My teaching is in general Public International Law, International Human Rights Law (IHRL) and International Humanitarian Law (IHL). I am the managing director of a Master's programme in International Human Rights Law at the Lund University Faculty of Law where I am also the course director of two obligatory courses. I also teach at the professional law degree programme, the programme for Peace and Conflict Studies, at the department for Gender Studies and the interdisciplinary Human Rights programme at the Department of History.
