His research interests focus predominantly on contemporary Greek politics and history. He is the co-author of The Limits of Europeanisation: reform capacity and policy conflict in Greece (Palgrave, 2008, with Featherstone). He has also published widely on a number aspects relating to Greek public policy, including welfare reform, privatisation and the labour market. More recently he has been working on the Muslim minority of Greece during the 1940s. His co-authored book The Last Ottomans: the Muslim Minority of Greece 1941-49 (with Featherstone, Mamarelis and Niarchos) will be published by Palgrave in 2010. Previously he has published Negotiating the New Europe (Ashgate, 2002) and From Marginalisation to Membership: Romania and the European Union (Routledge, 2008 with D. Phinnemore).
During his stay at the Hellenic Studies Program at Yale, he has worked on a new project focusing on the management of the Greek ‘core executive’ and prime-ministerial leadership styles in Greece since its transition to democracy. The project builds on an extensive set of elite interviews and places the operation of the Greek government in a comparative and theoretical perspective.
