My research focuses on geospatial data analysis and applications in coupled human-environment systems. I use satellite-borne multispectral data and airborne hyperspectral and 3-dimensional point cloud data in geospatial and environmental applications. The ecosystems I have studied include: grassland-forest ecotones, aspen communities and pinyon-juniper woodlands of the intermountain USA, sagebrush steppe in the northern Great Basin and Columbia Plateau, USA, and grassland steppe and Siberian larch forests of northern Mongolia
