Carbon Cycle And Ecosystems


My research interests lie at the intersection of geophysical data analysis, surface hydrology, and conservation ecology. My research primarily uses optical and thermal satellite image time series in conjunction with robust field measurements to better understand spatiotemporal landscape patterns. Ongoing work focuses on multisensor fusion related to the SMAP mission. Past work has focused on mapping and monitoring of oak landscapes in California Rangelands; chemical weathering severity in geologic outcrops; conservation and land use/land cover change in ecologically sensitive areas in Oman and Bangladesh; the application of spectral mixture analysis to the remote sensing of evapotranspiration; microscale physics of evaporation from porous media; intercomparison of information content in coincident multispectral and hyperspectral observations; and global standardization of Landsat and MODIS spectral mixture models.
