Dr. Martin Serrano is a recognized expert on semantic interoperability for distributed systems due to his scientific contribution(s) to using liked data and semantic formalisms like ontology web language for the Internet of Things and thus store the collected sensor’s data in the Cloud. He has also contributed to define the data interplay in edge computing using the linked data paradigm; in those works he has received awards recognizing his scientific contributions and publications. Dr. Serrano has advanced the state of the art on pervasive computing using semantic data modelling and context awareness methods to extend the "autonomics" paradigm for networking systems. He has also contributed to the area of information and knowledge engineering using semantic annotation and ontologies for describing data and services relations in the computing continuum. Dr. Serrano has defined the data continuum and published several articles on data science and Internet of Things science and he is a pioneer and visionary on proposing that semantic technologies applied to policy-based management systems can be used as an approach to produce cognitive applications capable of understanding, service and application events, controlling the pervasive services life cycle. A process called bringing semantics into the box, as published in one of his academic books. He has published 5 academic books and more than 100 peer reviewed articles in IEEE, ACM and Springer conferences and journals.Dr. Achille Zappais a Post-Doctoral Researcher at Insight, University of Galway. He received BSC/MSC degree in Biomedical Engineering and PHD in Bioengineering from the University of Genoa (Italy), his Ph.D. project was related to semantic web integration, knowledge engineering and data management of biomedical and genomic data and his research interests include semantic web technologies, semantic data mashup, linked data, big data management, knowledge engineering, big data integration, semantic integration in life sciences and health care, workflow management, IoT semantic interoperability, IoT semantic data and systems integration. Dr. Zappa is the W3C Advisory Committee representative for Insight Centre at University of Galway and member of W3C working groups like the HCLS IG, the Web of Things (WoT) IG and WG, the Spatial Data on the Web WG. He currently work with the main Insight Linked Data and Semantic Web Groups and with the UIoT (Internet of Things, stream processing and intelligent systems unit) Research Unit, addressing collaboration with different units and involvement in various projects where he seeks to develop general-purpose linked data analytics platform(s), which enables (a) flexible and scalable data integration mechanisms and (b) flexible use and reuse of data analytics components such as visualization components and analytics methods. Dr. Zappa has an extensive expertise of applying semantic web technologies and linked data principles in health care and life sciences domains.
