Building from a background in cartography and environmental cognition, my work during the 1990s focused on a range of issues associated with geographic representation and geovisualization. Within these domains, a long standing interest has been the interaction between formalized visual and digital representations inherent in maps and geographic information systems and human mental representation of space and space-time. In How Maps Work: Representation, Visualization and Design I develop a cognitive-semiotic theoretical perspective from which to address these and related issues. Much of my work deals with dynamic forms of representation. These forms exploratory spatial data analysis tools and map animation for understanding geographic processes.
Applications areas focused on in my geovisualization research have included epidemiological analysis, earth science education, implications of global environmental change, and uncertainty in health and environmental data and in meteorologicaland climatological model results.
My most recent research foci include integration of geographic visualization with other knowledge construction methods, natural interfaces to GIS, GeoVirtual environments, and geocollaboration (design and use of technologies to enable groups to work productively with geospatial information).
