Research interests

Dr Stefan focuses on European Union Law, in particular competition and state aid, constitutional and administrative law.

Her work combines socio-legal and doctrinal analysis, quantitative and qualitative methods, while exploring the limits of the rule of law, and questions related to new modes of governance and judicial politics.

Her recent book, Soft Law in Court, analyses the ways in which the Court of Justice of the European Union deals with soft law instruments in competition and state aid. Dr Stefan also engages with EU transparency studies.
