Areas of interest

Dr Gilder specialises in international peace and security primarily focusing on (1) UN peacekeeping and (2) human security in military operations, particularly those of NATO and its member states.

Alex has published widely on UN peacekeeping including on stabilization, counter-terrorism, the rule of law, the protection of civilians, and security sector reform. For example, his work has examined the rule of law activities of the UN in South Sudan (UNMISS) and the Central African Republic (MINUSCA), the legal implications of robust mandates and engagement with counter-terrorism by UN peacekeepers in Mali (MINUSMA), local engagement by the UN in Côte d’Ivoire (UNOCI), the role of UN peace operations in global health crises, and the future of protection of civilian mandates and their relationship with security sector reform. He has edited Multidisciplinary Futures of UN Peace Operations (Palgrave Macmillan 2023) and Peace Operations and Human Security (Special Issue in the Journal of International Peacekeeping).

His book, Stabilization and Human Security in UN Peace Operations (Routledge 2022), includes an analytical framework of human security that he applied to UN missions in Mali, CAR and South Sudan. He has used this framework in his work with the NATO HQ Allied Rapid Reaction Corps, where he has advised on the Military Contribution to Human Security (MC2HS), and in his engagements with other branches of UK defence.
