Biography
I am a member of the Information Systems group, working on a DPhil under the supervision of Prof. Georg Gottlob on Datalog+/-, a recently introduced family of languages for ontology querying. In particular, we are interested to identify expressive languages under which the conjunctive query answering problem is decidable, and study their complexity.
I received my MSc degree in Mathematics and Foundations of Computer Science from the Mathematical Institute of the University of Oxford in September 2007. My thesis was about data exchange and schema mappings under the supervision of Prof. Gottlob.
I received my BSc degree in Computer Science from the Computer Science Department of the University of Cyprus in June 2006. During my diploma project, under the supervision of Prof. Marios Mavronicolas, we studied the fully mixed Nash equilibrium conjecture. In fact, we identified a special case that verifies the aforementioned conjecture.
