I was born in Tripoli, Greece in 1978. In 2000 I received my BSc degree in computer science from University of Crete. In 2003 I received a MSc degree in computer engineering and in 2009 I received a PhD degree in information management both from Technical University of Crete.  During the periods October 2007 - December 2007 and March 2008 - July 2008 I joined the Databases and Information Systems Department at Max-Planck Institute for Informatics (MPII) as a visiting researcher under the supervisoin of Prof. Gerhard Weikum. Since August 2008 I am research and teaching staff at the Department of Informatics and Telecommunications of the University of Peloponnese, and member of the Software and Database Systems Laboratory (SoDa.Lab).  Finally, since July 2011 I am acting as an External evaluator for the FET-Open ICT Research Proposals in FP7 at the European Commission. My research interests lie in the meeting of distributed systems and data management, with extensions to data mining, databases, and digital libraries, and since 2002 I have (co-) authored around 20 papers in these fields. Most of them can be found here or (uncurated) at Google Scholar.
