Short Bio

My research work concerns the design and the use of (carto)graphic representations for geovisualization. I address knowledge, methods and tools to improve graphic representations (symbolization, stylization and rendering issues) for the visualization of geographic spaces and phenomenon, and the spatio-temporal analysis of urban and environment dynamics, while considering the diversity of users (public, scientists, practitioners).

Designing flexible and interactive geovisualization systems enabling visuo-spatial thinking and decision-making requires to observe user practices, to model uses and needs, such as to propose interactive methods to navigate into the space of possible rendering styles for geovisualization and visual analytics.

These purposes imply an interdisciplinary approach between GI sciences, geography, computer graphics, cognitive sciences, and human-computer interaction, about the understanding of geographic spaces and spatial data integration, representation and interaction.
