Cyril RAY is associate professor in computer science at Arts & Métiers and Naval Academy Research Institute (IRENav) in France. He obtained a Ph.D. from University of Rennes 1 in 2003 for researches on the modelling and the design of distributed simulation for transportation systems. He has done post-doctoral researches at INRIA on the conception of a Java operating system for mobile appliances. His current research is oriented to the modelling and design of location-based services applied to human mobility, maritime and urban transportation systems. This work includes, at different level, integration of location-based data, modelling of heterogeneous and large spatio-temporal datasets, movement data processing (cleaning, filtering, trajectory modelling, mining and knowledge discovery), modelling of context-aware information systems, traffic simulation and prediction, and security of information systems and data.He has mainly published in the domain of geographic information science, information systems, data management and analysis. He is currently associate editor of the International Journal of Geomatics and Spatial Analysis.Cyril RAY is active in the research field dealing with processing and analysis of maritime data under veracity issues. He has been leader of the project DEAIS funded by the national research agency (falsification of maritime identification systems) and is also currently involved in the European projects CISE DMS (Datamining Services for the EU CISE infrastructure) and H2020 Datacron (Big Data Analytics for Time Critical Mobility Forecasting).
