Over 25 years of experience in the development and assessment of atmospheric data assimilation systems, research in data assimilation and atmospheric predictability, observational field campaigns, atmospheric reanalysis, and assessment of observational data impacts on numerical weather prediction (NWP). Currently serves as the GMAO (610.1) Lead Scientist for Atmospheric Data Assimilation, leading the development of the NASA/GEOS-5 atmospheric data assimilation system, and overseeing NASA’s participation in the NASA-NOAA joint development of the Gridpoint Statistical Interpolation data assimilation scheme used in GEOS-5 and in the operational Global Forecast System (GFS) of the National Weather Service. Expert in the use of adjoint methods to evaluate atmospheric predictability and observation impacts on NWP.
