Profile for Saji Abraham

Affiliation: Wyle
Contact: E-mail
Office Phone: 301-286-8917
Saji Abraham received the Ph.D. degree in Space Physics from the University of Delhi, Delhi, India, the M.Sc. degree in Space Physics from Andhra University, Waltair, India, the M.S degree in Electrical and Computer Engineering with major in Photonics from The Johns Hopkins University, Baltimore, Maryland, and the B.Sc. degree in Physics from Kerala University, Trivandrum, India.
 
 He has been working as a scientist in supporting NASA projects since 1997. He is currently with Wyle Information Systems, LLC at Goddard Space Flight Center, Greenbelt, MD. He had been working on wide areas of ionosphere radio wave propagation techniques and published scientific articles on lower ionosphere dynamics and its coupling with the lower atmosphere through planetary waves and quasi-biennial oscillations. His expertise in interdisciplinary research activities includes the basic theory of electromagnetic interaction with matter, radiative transfer theory, land/sea/ice thermal emission models, surface roughness, atmospheric and ionospheric emissions, Faraday rotation and polarization mixing, celestial sky background that consist of solar, lunar, cosmic and galactic background emissions; professional research experiences in microwave remote sensing and academic experiences in laser, Infrared (IR) and Ultra Violet (UV) remote sensing. His research focuses on the development of forward models for space-born measurements to simulate brightness temperature and new approaches to derive Faraday rotation and sea surface salinity from Aquarius’ radiometric measurements at L band. Aquarius is NASA’s pathfinder space mission.
 

Dr. Abraham is a senior member of IEEE Geoscience and Remote Sensing Society and a member of the American Geophysical Union.
