Dr Alexander Gilder

Personal profile

Alex is a Lecturer in Law in the Department of Law and Criminology and Co-convenor of the International Law Subject Section of the Society of Legal Scholars. He has also been a Visiting Professor at the Institute for Peace and Conflict Studies, University of Hargeisa. Before joining the College, Alex taught at City, University of London and the University of Essex.

He specialises in public international law, especially areas related to international peace and security. His research currently follows two strands. First, Alex looks at themes related to stabilization in UN peacekeeping including robust force, counter-terrorism, and the effect of militarisation on other mandated tasks, such as entrenching the rule of law. Second, he is interested in the theory and history of international law and has worked on the relationships between the concept of human security, the individual, and international law. His research on these topics has appeared in journals, such as International Peacekeeping, Netherlands International Law Review, Indian Journal of International Law, Journal of International Humanitarian Legal Studies, and the Journal of International Peacekeeping. 

He is currently working on a monograph, under contract with Routledge, provisionally titled Stabilization and Human Security in UN Peace Operations. The book includes case studies on MINUSMA, MINUSCA, and UNMISS that examine whether the concept of human security can be seen in the UN's current stabilization activities.

Alex was previously the Editorial Assistant for the Journal on the Use of Force and International Law and sat on the Editorial Board of the Utrecht Journal of International and European Law.
