I am a physical geographer, geospatial scientist, and ecoclimatologist. I use satellites and tree rings to examine responses of terrestrial ecosystems to global change, especially in North American drylands.
MY LATEST RESEARCH
Forest growth in the U.S. responds asymmetrically to precipitation, implying reductions in tree growth as precipitation variability increases with warming.
We developed a set of phenologically-distinct ecoregions based on self-organizing maps and NDVI, solar-induced fluorescence, and vegetation optical depth.
