Geodetic sciences and remote sensing are my first specialties. Over the years, I have also developed expertise in fields such as environmental geomatics, as well as the extraction and classification of information from satellite images. In addition, I am involved in spatial modelling and the development of conceptual models and prototypes of geographic information systems (GIS). I also have strong interests in health geomatics in epidemiology, health infrastructure management and disaster management. Finally, I work on the geomatization of organizations (companies) through consulting and the implementation of GIS systems.
