I am interested in all aspects of geographic information systems, science, and technology. Accuracy and uncertainty are important issues in all of these areas, and involve the theoretical frameworks of fractals, geostatistics, and spatial statistics. I am interested in discrete global grids, a set of methods for representing variation over the curved surface of the Earth and implemented in tools such as Google Earth. I am interested in volunteered geographic information and in other paradigms for the production of geographic information. I am also interested in wayfinding and in urban mobility, including the long-term impacts of connected and autonomous vehicles.
