Summary: My research focuses on the development and application of satellite remote sensing to produce stable, well calibrated, and scientifically validated products from a series of earth observing satellites. My focus is on the quantification of uncertainty in satellite-derived products through a combination of quality assessment and validation techniques including day/night visible, near-infrared, and multi-angle imagery and measurements acquired from in-situ and airborne platforms.

At NASA, I am a member of the Suomi-NPP Land measurements team. As part of this joint NASA/NOAA effort, our team is currently tasked with developing and operating a Science Investigator-led Processing System (SIPS) to process and reprocess global land products from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument on the Suomi National Polar-orbiting Partnership (S-NPP) satellite to meet the needs of NASA Earth System Science and Applied Sciences communities. I am also the Land scientist for NASA’s Cloud Absorption Radiometer (CAR), considered one of the most frequently used airborne instrument built in-house at NASA Goddard, and an associate member (Co-I) of the MODIS science team.

I have also participated in several field campaign programs (e.g., FluxNetNACPARM-DoE, and BSRN) and intense observing periods (e.g., ChEAS’06, CLASIC'07, ARCTAS'08, ECO3D'11, and DISCOVER-AQ'14) to coordinate the production of in-depth accuracy and variability assessments for current and future reprocessing of global land and cryosphere products.

At the international level, my work focuses on addressing the challenges associated with the validation of Essential Climate Variables (ECVs) derived from satellite data by coordinating major field and airborne campaigns, managing a global network of validation sites, developing internationally-recognized validation protocols and standards, and ensuring that validation data and results are made available for free within the global user community.
