Interests: Remote Sensing, Spatial Statistics, GIScience, Land Cover Change.
Current Research: My research focuses on developing geo-spatial data analysis methodologies for monitoring and modeling environmental and ecological processes. It draws upon an array of geo-spatial and statistical approaches, particularly remote sensing and spatial statistics. While I have brought these approaches to bear on numerous research problems, a central theme in my research is the statistical modeling of the spatial or spatial-temporal dimension of the processes under study.
