He's now working on a project entitled 'The Uncertainty of Will,' which explores Shakespeare's vision on the connection between power and knowledge and examines its psychological and philosophical insights on human cognition and human institutions. 

He is the author of Constitutional Dilemmas- Conflicts of Fundamental Legal Rights in Europe and the USA (OUP, 2007) and numerous articles on human rights law and theory. His second monograph is entitled A Secular Europe: Law and Religion in the European Constitutional Landscape (OUP 2012). This is a study of one of the most pressing problems in Europe and includes issues such as the protection of religious freedom, the limits of religious toleration, and a wider debate on European identity.
