Dr. Vazirgiannis has a degree in Physics (Uni. of Athens), a MSc in Knowledge Based Systems (from Heriot Watt University, Edinburgh, UK). He acquired his Ph.D. in 1994 from the dept of Informatics, University of Athens. Since then, he has worked as an invited researcher in GMD-IPSI (now Fraunhofer) Germany, Fern-Universitaet, IBM India Research Laboratory, in Max Planck Instistut für Informatik (Saarbrücken, Germany) and in INRIA/FUTURS, Paris.
His research work ranges from Spatiotemporal databases to Data & Web Mining. He is currently interested in Web Mining (aspects of link analysis - time, predictive modelling), Text mining (similarity measures and their application in Word Sense Disambiguation), Distributed Data Mining & Machine Learning (Web search in P2P systems, dimensionality reduction, spectral analysis of the Web Graph & Social networks).
He has published more than 100 papers in international refereed conferences (among which ACM/SIGMOD, VLDB, ACM KDD, IEEE ICDE, ECML/PKDD) and peer reviewed journals (among which ACM TODS, IEEE TKDE, VLDB journal, ACM TOIT, IEEE JSAC) and two books with Springer Verlag. His work enjoys more than 4000 citations (according to Google - Scholar) - as of September 2009 - and has an H-index value 27 (according to "Publish or Perish"). His paper "A foundation for representing and query ing moving objects" is the top ACM/TODS journal paper for the decade 1994-2003 with regards to citations. His paper "Web Mining for Web Personalization", in ACM Transactions on Internet Technology (TOIT), volume 3, issue 1, 2003, was ranked 3rd most popular for 2004 in the ACM Digital Library.
Dr. Vazirgiannis has founded and leads the "DB-NET - Research team on Data & Web Mining". He is leading local research teams in several competitive international research projects (i.e. EU/IST projects) and has attracted more than 1.3MEuro funding in the last 8 years. He is leading also industrial projects in the area of complex B2B systems in the area of tourism.
He has participated in more than 30 programme committees for national and international conferences (among which VLDB, ACM-KDD, ECML-PKDD, IEEE-ICDM). He is PC co-chair of the ECML/PKDD 2011 Conference and is member of the "Intelligent Data Analysis" Journal (IOS press) editorial board.
Since 2005 he holds an Associate Professor position in "Database & Information Systems" in the Dept. of Informatics of Athens University of Economics and Business, Greece. Since 2008 he holds a visiting professor position in Ecole Polytechnique.
He has supervised seven Ph.D. theses, currently supervises five PhDs students and has participated as external examiner in more than 5 PhD committees in France, Germany and Spain. He has supervised more than 20 MSc theses - one of them, C. Doulkeridis, won the 2nd prize of "Michael Dertouzos competition" in the 14th World Congress on Information Technology - WCIT 2004. He has given more that 50 invited talks (among which 4 keynote speeches) and 5 invited tutorials in international conferences (among which SIAM/SDM, ECML/PKDD).
He has taught undergraduate and graduate courses in the areas of data bases, data/web/text mining, artificial intelligence and machine learning, in Greece (Univ. of Athens, Technical Univ. of Athens), Spain (Deusto University) while since 2008 he is teaching data bases in Ecole Polytechnique (Paris, France). He introduced 'Data Mining" as a taught course for the first time in Greece - in 1998 - at the University level.
He was awarded EU/TMR post-doctoral fellowships, the ERCIM fellowship (2001-2002) and was awarded an Intra-European "Marie Curie" Fellowship" (2004) to work in the area of P2P semantic web systems in INRIA-FUTURS (Paris) and the MARIE CURIE Reintegration Fellowship - thematic focus: P2P web search in 2008. In 2001 he earned the ERCIM Fellowship (European Research Council for Informatics and Mathematics), 2001. He participates in two patents (in the area of data and web mining).
He is active in a series of international research cooperations with Max Planck Institute (Germany), INRIA/FUTURS (France), Univ. of California at Riverside, USA, Yahoo! Barcelona, Microsoft @ Mountain View.
