My current research is oriented to the modelling and design of location-based services. My work mainly concerns theoretical aspects of the design of ubiquitous and adaptive location-based services applied to human mobility, maritime and urban transportation systems. This research addresses the relationship between geographic information systems and the underlying computing architectures that support real-time tracking of mobile objects (pedestrian in indoor spaces, vehicles in urban areas and ships at sea). This work includes, at different level, integration of location-acquisition technologies, modelling of heterogeneous and large spatio-temporal datasets, movement data processing (cleaning, filtering, trajectory modelling, knowledge discovery), modelling of context-aware systems and traffic simulation and prediction.
