Alistair’s main research interests are in the fields of European security, security studies, and the European Union. In particular: transboundary security challenges such as regional conflict and crises, terrorism, cybersecurity, and organised crime; EU internal and external security policies; Europe’s role in international security; NATO and Transatlantic security relations; conceptualising EU actorness and power, UK-EU security relations; and Brexit. Previously his research focused on the civilian and military aspects of the EU’s security and defence policy and its implications for the EU’s role as a security actor. Recently research projects include: 

A research monograph (2021) critically examining the nexus between European Union internal and external security threats and responses – the EU security continuum. This examines the extent and implications of the blurring of internal-external security for the EU. In particular, it studies the political, institutional, and ethical tensions the transboundary nature of security creates in formulating policy and identifying capabilities, and its impact on the nature of the EU as an international security actor.

A co-authored article (with Dr Michael Toomey) on 'Cultural Trauma, Historical Grand Narratives, and Brexit'. This examines the use of cultural trauma in debates and developments in British politics from David Cameron’s ‘Bloomberg Speech’ in 2013 to 2023. Having developed its theoretical framework on the construction of narratives it explains how such narratives have been deployed, particularly by pro-Brexit members of the Conservative Party before, during, and after the country’s withdrawal from the European Union.

An article on 'EU Counterterrorism, Collective Securitisation, and the Internal-External Security Nexus' in Global Affairs. The article examines the ways the EU has collectively securitised terrorism as a transboundary threat that blurs the traditional divide between internal and external security, requiring a multidimensional EU counterterrorism policy that transcends its institutional and capability silos. This collective securitisation of terrorism as a transboundary threat reshapes the nature of the EU as a security actor.

Currently, Alistair is working on two articles and is developing his next larger research project. 

First, an article on CSDP, EU Strategic Autonomy, and Strategic Culture in the Context of the War in Ukraine. While the war has galvanised efforts to develop CSDP’s strategic autonomy, longstanding obstacles of political will, funding, prioritisation, and capabilities continue to undermine the EU’s ability to realise it’s ambitions. Strategic culture is a key factor behind these obstacles and the EU's limited progress. Similarly, efforts to enhance CSDP, respond to Russia’s aggression, and address the wider transboundary threat environment continue to be shaped by strategic and pull the EU in differing directions. 

Second, Alistair is in the early stages of a paper on the ways in which the EU has discursively and in practice contributed to the emergence of a nexus between security, migration, and development. The EU has collectively securitised migration in a way that increasingly interconnects what were traditionally internally and externally oriented departments, agencies, and institutions, and internally and externally policy tools and capabilities (notably civilian and military tools), in the pursuit of a ‘comprehensive approach’ to migration as a transboundary security threat. 

In the longer term, Alistair is developing a project on European Strategic cultures in the wake of the War in Ukraine and the implications for NATO and the EU's ambition for Strategic Autonomy in defence.
