Personal Information

Studies. I was born in Athens in 1972. I graduated the Varvakio Experimental School in 1990 and obtained my Diploma in Electrical Engineering and my PhD from the Department of Electrical and Computer Engineering, of the National Technical University of Athens (NTUA) in 1995 and 2000, respectively. During that period, I was a member of the Knowledge and DataBase Systems Laboratory (KDBSL) of NTUA (my old homepage@KDBSL)

Positions. I have joined the Department of Computer Science of the University of Ioannina in 2002 and since then, I am a member of the Distributed Management of Data (DMOD) Laboratory. Prior to this appointment, I have also worked as a short-term professor at the Department of Electronic and Computer Engineering of the Technical University of Crete and the National Technical University of Athens.

R&D. I have worked for DataBlue Greece, during 1995 and 1996. I have also worked for several ESPRIT (ALEXANDER, TOOBIS, DWQ) and IST projects (EDITH, PANDA). Other research projects include project "Object-Oriented Model for the representation of multimedia and multimedia applications" (PENED 95ΕΔ3.3.2-564) and project "Data Quality in Decision Support Systems" under the French-Greek Cooperation Programme "Plato", for NTUA and the General Secretariat of Research and Technology of Greece. Moreover, I have worked in applied projects, such as "Ippokratis", for Datablue Greece and "Technical Support for the General Accounting Office of the Greek Ministry of Finance for Database Issues" for ICCS-NTUA.

Research. Untill now, my research has mainly focused on Data Warehouse and Business Intelligence technology, with particular interest on issues like Data Warehouse Metadata Repositories and Metadata Modeling, Data Warehouse Quality, On-Line Analytical Processing (OLAP), and Extraction-Transformation-Loading (ETL). Currently, apart from the continued interest in data warehousing and business intelligence, with particular emphasis on re-inventing data analytics on the basis of intentional operators and data storytelling, my on-going research is also targeted towards the study of Schema Evolution with particular emphasis to the uncovering of mechanisms, patterns and forecasts for the evolution of schemata as well as Software Engineering with particular emphasis to pattern-based design.

Professional Activities. I have served as a reviewer for various journals (including VLDBJ, Information Systems, IEEE TKDE, DKE, DAPD, DSS, JODS, IST and others) and as a PC member in several conferences. I have served as an Editor-in-Chief for the Journal on Data Semantics, Springer. I have served as a a track co-chair for ICDE 2009 ("DW, OLAP and data grids" track) and CIKM 2009 in the "Knowledge Management"Track (responsible for the areas "Data pre- and post-Processing", "Information Filtering and Recommender Systems", "Knowledge Synthesis and Visualization"). Moreover, I have served as a PC chair for DMDW 2003, ParMa 2004 and ParMa 2006, DOLAP 2006, HDMS 2009, QDB 2010 and ADBIS 2023.

Memberships. I am a senior member of both ACM and IEEE.
