Yannis Tzitzikas is currently Associate Professor of Information Systems in the Computer Science Dep. at University of Crete (Greece) and Affiliated Researcher of the Information Systems Laboratory at FORTH-ICS (Greece). Before joining UofCrete and FORTH-ICS he was postdoctoral fellow at the University of Namur (Belgium) and ERCIM postdoctoral fellow at ISTI-CNR (Pisa, Italy) and at VTT Technical Research Centre of Finland. He conducted his undergraduate and graduate studies (MSc, PhD) in the Computer Science Department at the University of Crete. In parallel, he was a member of the Information Systems Lab of FORTH-ICS for about 8 years, where he conducted basic and applied research around semantic network-based information systems in the context of several EU-founded research projects. His research interests fall in the intersection of the following areas: Information Systems, Information Indexing and Retrieval, Conceptual Modeling, Knowledge Representation and Reasoning, and Collaborative Distributed Applications. Currently his research focuses on: exploratory searching (principles, techniques, applications), semantic data management (comparison functions, knowledge evolution, indexes, visualization, integration), and methodologies and technologies for building advanced information systems for digital preservation. The results of his research (mainly conducted with students) have been published in more than 100 papers in refereed international conferences and journals, including prestigious journals and venues (e.g. ACM Transactions on the Web, VLDB Journal, IEEE Transactions on Knowledge and Data Engineering, JIIS, JDAPD, ECIR, ISWC, EWSC), and he has received two best paper awards (at CIA'2003 and ISWC'07, and other awards). He has supervised two PhDs and more than 20 Diploma and 15 MSc theses, and he actively participates in EU projects having achieved more that 700K Euros funding the last 5 years. Finally he regularly participates to the scientific committees of several international conferences and journals. A more detailed CV is available here.
