Areas of interest

Dr Gilder works on areas related to international peace and security, such as UN peace operations, peacebuilding, and human security. His research is interdisciplinary, drawing on perspectives from law and international relations. Alex investigates various aspects of UN peacekeeping including stabilization, counter-terrorism, the rule of law, the protection of civilians, and security sector reform. His research has also applied the multidisciplinary concept of human security to examine the role of the individual in international law. 

Alex has published on the aforementioned topics as well as other areas of international law including the law of occupation, international human rights law, and the law on the use of force. His research has appeared in journals and volumes, such as International Peacekeeping, the Journal of International PeacekeepingGlobal Policy, the Netherlands International Law Review, the Indian Journal of International Law, the Journal of International Humanitarian Legal Studies, the Wisconsin International Law Journal, the NYU Journal of International Law and Politics, and the Palgrave Encyclopedia of Peace and Conflict Studies.

His monograph, Stabilization and Human Security in UN Peace Operations (Routledge 2022), includes case studies on Mali (MINUSMA), the Central African Republic (MINUSCA), and South Sudan (UNMISS) that examine whether the concept of human security can be seen in the UN's current stabilization activities.
