    Positions/Employment

    12/2015 - Present

    Research Physical Scientist

    NASA Goddard Space Flight Center, Greenbelt, MD

    Conduct research on Earth science remote sensing measurement and modeling to understand their impact on land-atmosphere interactions and relationships with human activities through the analysis of data from space, in-situ and airborne instruments. Serve as the technical lead for transitioning the award-winning Land Information System (LIS; http://lis.gsfc.nasa.gov) for research and applications with partners at the Air Force Weather Agency, NOAA/NCEP, USACE, USDA, NRL,NWS/OHD, NCAR, NOHRSC and USGS/FEWSNET. The targeted use of LIS span socially relevant applications such as water resources and agricultural management, drought and flood monitoring, famine early warning and prediction and weather and climate prediction.
