Information
Personal information / Education: Nikos was born in 1975, he received his B.Sc. degree from the Computer Science Department of the University of Crete (1998). He has subsequently joined the Department of Computation in the University of Manchester Institute of Science and Technology (UMIST) to pursue his M.Sc. in Information Systems Engineering (1999) and his Ph.D. in Moving Object Databases (2002).
Professional information: Nikos is a Lecturer at the Department of Statistics and Insurance Science, School of Finance and Statistics, University of Piraeus, Greece. Before, he was a free lancer for software houses, while since 2004 he was post-doctoral researcher at the Information Management Lab (InfoLab, http://infolab.cs.unipi.gr/) of University of Piraeus.
Research: Nikos’ research interests include data mining, spatiotemporal databases, management of location-based services, machine learning and geographical information systems, whereas he teaches respective courses at under- and post- graduate level. He has been particularly working for almost ten years in the field of Mobility Data Management and Mining, being the architect of the widely cited “Hermes” Moving Object Database (MOD) engine. He has offered several invited lectures in Greece and abroad (including PhD/MSc/summer courses at Rhodes, Milano, KAUST, Aalborg, Trento, Ghent, JRC Ispra) on Mobility Data Management and Data Mining topics. He is a reviewer in many international journals and conferences. He has served as co-Organizer of a EURO Stream on data mining and knowledge discovery (DMKD@EURO’09).  He has been member of the Organizing Committee for ECML/PKDD 2011. He has been actively involved in more than 10 European and National R&D projects. Among them he is or was principal researcher in GeoPKDD (FP6/IST, 2005-09), MODAP (FP7/ICT, 2009-12), MOVE (COST, 2009-13; substitute member of the mgmt committee), DATASIM (FP7/ICT, 2011-14) and SEEK (FP7/PEOPLE, 2012-15). Currently, Nikos is leading the research activities of InfoLab.
Publications: Nikos has co-authored one monograph and more than 50 refereed articles in scientific journals and conferences, receiving more than 300 citations. The following list includes five selected publications:
