 Nikos Lorentzos is a Professor at the Agricultural University of Athens. He has a first Degree in Mathematics (National and Kapodistrian University of Athens, 1975), a Masters Degree in Computer Science (Queens College, CUNY, USA, 1981) and a PhD Degree in Computer Science (Birkbeck College, University of London, 1988). He is an expert in databases with major research contribution in Temporal, Spatial and Spatiotemporal Databases and on the development of DSSs and Expert Systems in the forestry and agricultural domain. His research approach on temporal databases can be found in books of international circulation, addressed to students and to professionals. His work has influenced the ISO/DBL/WG3 group, working on the SQL standards, as is witnessed by several ISO reports that proposed the inclusion of pieces of his research on temporal databases into SQL Temporal, in reaction to a competitive approach, proposed by an international group. Today, SQL:2011, the unique ISO language for the management of relational data contains temporal constructs based on two PhDs, one PhD by him and another PhD, supervised by him at the Agricultural University of Athens. Follow up research abroad has been based on his approach on temporal databases. He has acted as a member of an international group, which worked on a temporal extension to SQL (publication of book with international circulation). He has participated in many research projects. One of them (ORES, ESPRIT III), concerned the temporal dimension of information systems. He was the Technical Manager of the project and the prime researcher for the development of a Temporal Database Management System. In another project (CHOROCHRONOS, TMR), he was the prime researcher for the formalization of a spatial and of a spatiotemporal DMBS. He has 33 publications in international journals, 2 in Greek journals, 53 publications in international and Greek conferences, 12 book publications (4 in Greek books), 3 lemmas in an encyclopaedia of international circulation, 1 contribution in a book of international circulation and 1 book publication. He is also the co-author (with Christian J. Date and Hugh Darwen) of a book on Temporal Databases, of international circulation (already, an impoved version, under a new title). On 15/04/2014, citations to his research work exceeded 2800. Many of them refer extensively to his research and evaluate it with positive comments. He has supervised three (3) PhD Dissertations as well as Post Graduate and Undergraduate Diploma Theses. He was the invited speaker of many events, mainly in Europe and also in the USA. He has acted as a reviewer for many major international journals and conferences, as evaluator of projects for the European Union and as examiner of PhD Dissertations in Europe. In Greece, he has offered his experience in information systems to the Ministries of Interior Affairs, of Economics, of Development and of Education, as well as to the Greek Scholarships Foundation, National School of Public Administration and the Superior Council of Personnel Selection. In the Agricultural University of Athens, he has acted as President or Member of many committees, with major emphasis on issues related to the automation of the University and the development of information systems.
