Eni Njoku

MLK Visiting Scholar 2001-2002 Senior research scientist, NASA Jet Propulsion Laboratory, California Institute of Technology
Through our scientific and technological genius, we've made of this world a neighborhood. And now through our moral and ethical commitment, we must make of it a brotherhood.
— Dr. Martin Luther King Jr.

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).
