Dr. Prof. Kyriakos Kritikos (M) obtained his BSc, MSc and PhD in Computer Science from the University of Crete. He was an ERCIM Post-Doc researcher in CNR, Italy and FNR, Luxembourg and as well as a Post-Doc researcher at Politecnico di Milano. He was also a Research Collaborator at the Information Systems Laboratory (ISL) in the Institute of Computer Science (ICS) at the Foundation for Research and Technology - Hellas (FORTH). He is currently an Associate Professor in the Department of Information and Communication Systems Engineering at the University of the Aegean as well as an Affiliated Researcher in ISL at ICS-FORTH. He has been involved in many European and national projects, including S-Cube, PaaSage, CloudSocket and Melodic. He has also many publications in highly prestigious journals (16) and conferences (61), including ACM Computing Surveys & IEEE Transactions on Services Computing, as well as in books (5). He has been a reviewer in numerous conferences (>70) and journals (>30) while he is currently a member of the editorial board in two Elsevier journals: (a) Journal of System and Software and (b) Array. Dr. Kritikos was a program co-chair of the ESOCC 2018 conference in Como, Italy as well as a program chair of the BPM@Cloud workshop at ESOCC 2017 in Oslo. He is also the main organizer of the ESOCC 2020 conference in Heraklion, Crete, Greece. He is one of the founders of the state-of-the-art cloud application modelling language called CAMEL as well as the developer of the OWL-Q language for the semantic description of services, SLAs and KPIs. His most influential work also includes the proposal of a semantic algorithm for the matching of QoS metrics as well as various kinds of non-functional service matchmakers. His research interests span: cloud deployment reasoning, semantic service description, discovery and composition, service negotiation, cross-layer service monitoring and adaptation, goal-driven business service design, interactive service-based application design, SLA and KPI modelling & assessment, security modelling, risk assessment, ontology reasoning and constraint programming.
