**Still off - Not at working since November 2023**
My research works concern the design of methods of 2D/3D (carto)graphic representation and interactive exploration of nD geospatial data, enabling the interpretation and the understanding of spatio-temporal phenomena on earth, through visual (or non visual)-spatial thinking. This implies an interdisciplinary approach between geographic information sciences, human-computer interaction and computer graphics.
GI Sciences & Systems, Geovisualization, Map design, Visual rendering, Graphic Semiotics, Perception, Spatial Immersion.
