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. I have joined the Department of Computer Science and Engineering of the University of Ioannina in 2002 and since then, I am a member of the D.A.T.A Laboratory. So far, my research has focused on Data Warehouse 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, my on-going research is targeted towards ...
- the study of how schemata evolve [Schema biographies]
- a paradigm shift towards a new OLAP [OLAP III]
- the modeling, design, representation, and, evolution of Metadata-Rich Data-Intensive Information Systems [Hecataeus project]
All the software developed by my DAta INTensive Information EcoSystemS Group is available on-line as free and open-source software on github.
