Dimitrios Kyriazis's Research

Dimitrios’ research focuses on the interaction between EU State aid rules and national tax measures, exploring, in particular, the extent to which EU state aid policy can serve as a tool against harmful tax competition between Member States. In this context, emphasis is placed on the recent European Commission investigations into multinationals’ tax arrangements (e.g. the Apple, Fiat & Amazon cases).

His research, which lies at the intersection between public law, EU law and international tax law, has been supported by numerous scholarships and awards including the Clarendon scholarship (University of Oxford), the Onassis Foundation and the Chartered Institute of Taxation.

Dimitrios has published widely in legal journals and online media.
