  • Associate Professor of International Law and Security

Co-Director, Postgraduate Taught Programmes

Deputy Director, Global Law at Reading (GLAR)

Areas of interest

Dr Gilder works on areas related to international peace and security, such as UN peace operations, peacebuilding, and human security. One of the few international lawyers working in the peacekeeping space, his research is necessarily interdisciplinary, drawing on perspectives from law, peace and conflict studies, 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. 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.

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. You can hear more about this research on the Humans of Security podcast or on YouTube. He is also the lead editor of Multidisciplinary Futures of UN Peace Operations (Palgrave Macmillan 2023).

His next book, Peace Operations: Law, Policy and Practice, will feature in Edward Elgar’s Principles of International Law series. Targeted at researchers, students and policymakers, the book will provide interdisciplinary coverage of contemporary peace operations including the law applicable to peacekeepers and current trends, such as stabilization and the protection of civilians.

His research has also applied the multidisciplinary concept of human security to examine the role of the individual in international law and has published on other areas of international law including the law of occupation, international human rights law, and the law on the use of force. He is currently a Consultant at the NATO HQ Allied Rapid Reaction Corps where he is advising on the Military Contribution to Human Security (MC2HS).
