SUMMARY:
 
I'm a NASA Earth System Scientist with a knack for turning complex pixels into useful data. My research focuses on the development and application of satellite remote sensing to produce long-term, stable, well calibrated, and scientifically validated measurements that can improve our understanding of human-climate-ecosystem interactions.
 
Most recently, my work has focused on characterizing variations in global energy service demand by understanding how dominant social phenomenon, the changing demographics of cities, and the socio-cultural setting within which people operate affect their energy decisions and use patterns.
 
At NASA Goddard, I lead multiple investigations, including the Land Product Validation (LPV) activities surrounding the EOS Terra/Aqua MODIS and Suomi-NPP VIIRS instruments, as well as field-based and airborne experiments using current (CAR/P3B) and future (MALIBU/Tempest) airborne measurement suites. At the international level, I also serve as an elected officer on the Committee on Earth Observation Satellites (CEOS) Working Group on Calibration and Validation (WGCV).
 
I have a strong passion for STEM education and public outreach, with a particular focus on increasing climate science literacy in Spanish speaking communities across the US and Latin America. I also serve as program advisor to national organizations that support underrepresented groups, and as mentor to NASA postdoctoral fellows, visiting faculty, and students from minority serving institutions. I am also media trained and receive regular press coverage on television, radio, print, and online news media programs.

Recent Meetings, Interviews, and Presentations

M. Román produced the first continuous time series of VIIRS nighttime lights over the Nepal region. The preliminary datasets are being used by multiple end-user groups (e.g., NASA-SPoRT, UNESCO-Nepal, Stanford Geospatial Center, Mapbox, and the USGS Hazards Data Distribution System) to characterize widespread power losses after the earthquake. Images produced by Jesse Allen (SSAI/613) are now available on NASA's Earth Observatory: http://earthobservatory.nasa.gov/IOTD/view.php?id=85816&eocn=home&eoci=iotd_grid.
