Curriculum Vitae
Research
My long-term projects will continue to focus on biophysical/ bioenvironmental geography and disturbance, particularly fire and disease. I incorporate remote sensing and spatial information systems to understand processes producing natural spatial patterns, and the effects of disturbance on these processes and patterns. This work involves biophysical characterization of status and change in vegetation systems, using passive and active remote sensors, spatial statistics and simulation modeling, and examines the basis for and geographic implications of changes in these systems. The information systems portion of my research involves, over the long term, data integration and modeling. This includes use of spatial statistics to examine the scale-dependence of natural phenomena, resolution of scale disparities, and characterization of errors in spatial databases. I am interested in research projects that exploit remote sensing applications of earth system science. Beyond development of geospatial information technologies that advance pyrogeography, I would like to expand pyrogeography into more theoretical areas, examining whether earth systems in 'deep' time (i.e., paleohistorically) were more or less resilient to natural fire disturbances, and whether potential changes in climate will affect in fundamental ways the basic source-sink feedback mechanisms that mediate the biogeography of earth's vegetation. I wish to add also more applications work in the area of geospatial decision support, including remote sensing applications that exploit urban-environmental interactions.
