My PhD thesis examines the socialising effects of the European Union (EU) foreign policy regime on the behaviour and identities of EU member state diplomats within the North Atlantic Treaty Organisation (NATO) and the Organisation for Security and Co-operation in Europe (OSCE). I also continue to conduct research and have published various pieces on different aspects of EU-NATO cooperation, the OSCE Corfu Process, the European External Action Service and the the evolution of the EU's Common Security and Defence Policy. In the past, I have worked inter alia with the OSCE Section of the Delegation of the European Union to the International Organisations in Vienna, the European Union Institute for Security Studies, the OSCE and the European Centre for Development Policy Management.
