Présentation
I studied Electrical Engineering at the National Technical University of Athens (NTUA) in 1988, I received my DEA in computer science from the University PARIS VI in 1992, and my Ph.D. from the Conservatoire National des Arts et Metiers (CNAM) of Paris, in 1996. I am currently Professor of Computer Science at ENSEA, Cergy. Previously, I have served the Computer Science Department of the University of Crete for 5 years as Associate Professor and 11 years as Full Professor (Professeur grade 1). Between 2019 and 2020, I was fellow in residence (Adjunct Professor) at the Institut d’Études Avancées (IEA), Université CY Cergy Paris. From 2015 to 2019 I have been elected to an advanced research position at INRIA-Paris while from 2013 to 2015 I have worked as a Distinguished Scientist at Technicolor, R&I Center in Paris.
My main research interests span Machine Learning Systems, Data Science and Big Data Computing, Databases and Web Information Systems, as well as Digital Libraries and Scientific Systems. On these topics, I have published 148 articles in leading journals and conferences. My research work was driven by the need to manage, process and analyze post-relational data (semi–or unstructured) in centralized, distributed and streaming settings often in the context of other scientific fields (e.g., Cultural Heritage, Environmental Sciences, Educational Sciences, etc.). My work has received 7000 citations with an h-index 44 according to Google Scholar.
I was a recipient of the 2004 SIGMOD Test of Time Award, and of several best paper awards in ISWC (2003, 2007, 2009). I chaired (General Chair of the EDBT/ICDT Conference in 2014, Area Chair for the “Semi-structured, Web, and Linked Data Management” track in ICDE 2016, Chair of the Web Services Track in SCC 2004, Industrial Track Chair in EDBT 2004) or served on program committees of numerous conferences (VLDB, ICDE, EDBT, WWW, CIKM, etc.) while I have acted as editorial member, or reviewer of several journals (CACM, TODS, TOIS, TOIT, VLDB Journal, TDKE, DPS, etc.). I have also been a keynote or invited speaker in conferences and summer schools (PODS 2003, HDMS 2004, ESWC Summer School 2013, WebST 2016, BDA Summer School 2018).
