Academic Social Networks:

D. Gavalas is employed as Professor in the Department of Product and Systems Design Engineering in the University of the Aegean, Greece (Head of Department as of September 2020), and Adjunct Professor in Hellenic Open University.

Over the past few years he has conducted research in the fields of mobile/pervasive/distributed computing, augmented/virtual reality, wireless adhoc networks, optimizations algorithms, transportation systems, web technologies, mobile code, network and systems management, e/m-commerce.

He has co-authored over 185 publications on the above subjects, published in international journals, book chapters and conference proceedings, which have received over 5000 citations (h-index: 36, i10-index: 85). He has also co-authored three books (written in the Greek language) covering the thematic areas of wireless networks, distributed systems and mobile technologies, respectively. He has been ranked among the 100.000 top scientists across all fields - top 2% in the field “Networking & Telecommunications”, based on his career-long research performance according to a recent survey of PLoS Biology (2020).  

He has extensive teaching experience in both undergraduate and postgraduate level, in courses related to web design and development, web-based multimedia, hypermedia technologies, computer networks, electronic commerce, databases fundamentals, distributed systems, mobile & pervasive computing and wireless networking.
He has supervised three completed PhD dissertations and dozens of final year and MSc projects.

He serves as editorial board member of Journal of Network and Computer Applications (Elsevier), Personal and Ubiquitous Computing (Springer), Information Technology & Tourism (Springer) and Sensors (MDPI). He has co-chaired the IEEE WiMob 2020 conference as well as the MobiSensor (2010-2012) and ISUT (2017-2018) international workshops.He has also served as TPC member in numerous (> 100) leading conferences and guest-editor in highly ranked journals in the fields of mobile and wireless communications.

He has acted as external reviewer for research proposals submitted to H2020 FET OPEN, Research Promotion Foundation (Cyprus), Italian  Ministry  for  Education,  University  and  Research (MIUR),  Polish National  Science  Centre (NCN), Greek General Secretariat for Research and Technology (GSRT), etc. He has participated as a coordinator and/or key researcher in several research and development projects funded by Greek national and European funding bodies, including TouristHub and SocialPARK (GSRT), SMARTBUY (H2020-ICT-2015/687960), HoPE (EC/CIP7/621133), MOVESMART (EC/FP7/609026), eCOMPASS (EC/FP7/288094), VESPER (EC/IST-1999-10825), OPTIMIST (EC/IST-1999-12501).
