Curriculum Vitae:

James S. Famiglietti
Group Supervisor

Jay Famiglietti is JPL's Senior Water Scientist, Chief Scientist of the Western Water Applications Office and Project Scientist for the Western States Water Mission. His team uses NASA satellite observations and develops advanced hydrological models to explore global water cycle change and changing freshwater availability. His group's work using the GRACE mission to characterize groundwater depletion was the primary justification in the 2010 NASA Climate Architecture report for the selection of the GRACE-FO as a climate continuation mission.
