Dorothea Kalogianni is currently a PhD candidate at the Edinburgh College of Art, of the University of Edinburgh, where she is also a tutor. Her doctorate research links neuroscience, digital media and sound. More specifically she investigates the affective responses that digitally mediated sonic environments have on the spatial behavior of the users. She has worked on responsive arts installations and has been exploring electroencephalography (EEG) technology for the creation of affective responsive environments. She received her graduate diploma in architecture from the Aristotle University of Thessaloniki (Greece) and has completed the Msc in Adaptive Architecture and Computation at the Bartlett School of Architecture of the University College of London. She is an AHRC funded student (tuition fees only-year 2 and 3) and a registered Greek architect.

He has published 2 journals and 9 conference papers. Athanasios received his first B.Sc. degree in Business Planning and Information Systems from TEI of Patras, and his second B.Sc. degree in Informatics from University of Piraeus. He also holds an M.Sc. in Advanced Computer Systems from the same University. Additionally he held a scholarship from the Institute for the Management of Information Systems, Research Center "Athena" in the research area of "Privacy protection". Currently he is an employee of ERT A.E.
Kleanthis Dellios has received his PhD and post-doctoral research certificate in Information Security at the University of Piraeus, Greece, whose main areas of interest are IoT cyber-security robustness, information security (threat and risk) management and critical infrastructures’ protection. Dr. Dellios is a certified ISMS Auditor (ISO/IEC 27001), has worked as a Q/A software tester in a consortium of private companies on behalf of DG-TAXUD (ECICS2, EBDI, and TARIFF) and participated in funded research projects (EU and NSRF) that vary from secure immigration policies, maritime/port ISMS, behavioral revocable biometric identification, e-cultural heritage to automation engineering. Dr. Dellios is currently an Interim Agent – NIS expert at European Union Agency for Network and Information Security (ENISA), supporting the development of ICT security standards frameworks and implementation in Europe and Member States.


Agusti Solanas is the head of the Smart Health Research Group and Serra Húnter Fellow and Associate Professor in the Department of Computer Engineering and Mathematics at the Rovira i Virgili University (URV) of Tarragona, Catalonia, Spain. He obtained his M.Sc. degree in Computer Engineering from URV in 2004 with honours (Outstanding Graduation Award). He received a Ph.D. in Telematics Engineering from the Technical University of Catalonia in 2007 with honours (A cum laude). In 2012, he was visiting researcher in the Department of Mathematics and Physics of the University of Rome Tre (Italy), and in 2013, he was visiting researcher in the Department of Mathematics of the University of Padua (Italy). He has participated in several European-, Spanish-, and Catalan-funded research projects. He has authored over 100 publications and he has delivered several invited talks worldwide. He is senior member of the Institute of Electrical and Electronics Engineers (IEEE) and member of the Association for Computing Machinery (ACM). Currently he is the vice-president of the Computer Society Spain Chapter. His fields of activity are mobile health, smart health, cognitive health, data privacy, ubiquitous computing, and activity recognition.
Constantinos Patsakis is an Assistant Professor in the Department of Informatics, at the University of Piraeus, Greece. He holds a B.Sc. in Mathematics from the University of Athens, Greece and a M.Sc. in Information Security from Royal Holloway, University of London. He obtained his PhD in Cryptography and Malware from the Department of Informatics of University of Piraeus. His main areas of research include cryptography, security, privacy, data anonymisation and data mining. He has made more than 70 publications in peer reviewed international conferences and journals and he has been teaching computer science courses in European universities for more than a decade. Dr Patsakis has been working in the industry as a freelance developer and security consultant. He has participated in several national (Greek, Spanish, Catalan and Irish) and European R&D projects. Additionally, he has worked as researcher at the UNESCO Chair in Data Privacy at the Rovira i Virgili University (URV) of Tarragona, Catalonia, Spain and as a research fellow at Trinity College, Dublin Ireland.
