Profile

I am Professor of International Law at the University of Sheffield, joining the University in 2012 from the University of Glasgow where I was Professor of International Law and Security. I completed my law studies at the University of Thessaloniki in Greece, obtaining an LL.M. from the University of Bristol and my Ph.D from the University of Nottingham. My teaching and research interests are in the fields of international law and the use of force, international humanitarian law, international criminal law, collective security law, peacekeeping, United Nations Law, international and European constitutional theory and law and cybersecurity. I am widely published in these fields.

I am Director of the Sheffield Centre for International and European Law. I sit on the editorial board for the Journal of Conflict and Security Law and for the Journal on the Use of Force and International Law. I am convenor of the European Society of International Law Interest Group on Peace and Security. I am member of the AHRC Peer Review College. I hold a visiting post at the University of Umea, Sweden and have taught at many Universities in Europe and the USA.
