The trailblazers in human, academic, scientific and religious freedom have always been in the minority… It will take such a small committed minority to work unrelentingly to win the uncommitted majority. Such a group may transform America’s greatest dilemma into her most glorious opportunity.
Background
Eni G. Njoku is a research scientist in the NASA Jet Propulsion Laboratory (JPL) at the California Institute of Technology. Njoku holds a BA in electrical sciences/natural sciences from Cambridge University (Clare College) in England. He earned both an MS and PhD in electrical engineering from MIT.
Interests
Njoku explores applications of spaceborne microwave sensing to studies of land surface hydrologic processes and the global water cycle. In his early years at JPL, he was section manager of the Geology and Planetology Section at JPL, and two years later joined the Aqua Advanced Microwave Scanning Radiometer (Aqua/AMSR-E) science team. In 2001, Njoku was appointed project scientist of the Hydros Mission and principal scientist. Additionally, Njoku served as program scientist for the Ocean Processes Branch and Earth Science Data and Information Systems at NASA headquarters (1986-1990). His exceptional research earned him a NASA Exceptional Service Medal (1985) and four NASA Group Achievement Awards (most recently, the 2013 Award to the SMAPVEX12 Field Campaign Team).
