His recent work has focused on the EU and NATO as security actors, the transformation of security politics, and the development of international prevention and intervention efforts of the EU, the OSCE, and NATO, more generally. He has also specialised on the European Union in the Southern Caucasus (Georgia, Armenia, Azerbaijan) and covers - among others - geopolitical aspects of EU energy supply. In a current project, Mr Mayer seeks to explain Russian and EU security policies towards their shared neighbourhood since 1991 and related dynamics of interaction between the two polities.
