    About me

    I am a spatial ecologist with expertise in Landscape Ecology, Conservation Ecology, Remote Sensing, GIS, and spatial and statistical analyses.  My research focuses on the application of geospatial methods to conservation planning and assessment, landscape ecology, and biodiversity research.  It combines remote sensing with GIS, and statistical and simulation modeling to address processes across levels of organization (i.e., organismal through landscape processes) and conservation strategies at a range of scales.  Much of my research has stemmed from the development and demonstration of broad-scale, spatially-explicit environmental monitoring frameworks using Earth observation data.  The resultant data products, of invasive plant distributions and important environmental gradients, are invaluable for environmental management, including the conservation of biodiversity and ecosystem services, as well as basic ecological research.  I have applied these products to develop models of invasibility and population spread, to evaluate the effects of habitat fragmentation, to probe the mechanisms underlying broad-scale biodiversity gradients and patterns of community composition, and to assess the effectiveness and future potential of protected area networks.
