Positions/Employment


Lead Research Scientist

SSAI - Greenbelt, MD

2014 - Present

NASA VIIRS calibration and support team

  • Developed core algorithms related to the SNPP VIIRS on-orbit radiometric calibrations of its reflective solar bands
  • Generated on regular basis Look-up-tables for the SNPP VIIRS reflective solar bands on-orbit radiometric calibrations


Principal Support Scientist

SSAI - Greenbelt, MD

2010 - 2014

NASA VIIRS calibration and support team

  • Developed a mathematical model to describe the Suomi NPP VIIRS telescope mirror reflectance degradation due to exposure to solar radiation and used the model to project future sensor’s radiometric response for the reflective solar bands
  • Developed core algorithms related to the SNPP VIIRS on-orbit radiometric calibrations of its reflective solar bands
  • Generated on regular basis Look-up-tables for the SNPP VIIRS reflective solar bands on-orbit radiometric calibrations
