Biography

Stefania joined FSE as a research data analyst in March 2018 where she works with David Lobell on designing, implementing, and applying new satellite-based monitoring techniques to study several aspects of food security. 

Her current focuses include estimates of crop yields, crop classification, and detection of management practices in Africa and India using a variety of satellite sensors including Landsat (NASA/USGS), Sentinel 1 and 2 (ESA), combined with crop modeling and machine learning techniques.

Lasering In on Corn Fields

Mapping crops around the globe is key to estimating production and developing targeted management strategies. New research utilized data from NASA's Global Ecosystem Dynamics Investigation (GEDI) technology and developed an algorithm to distinguish between maize and other crops with high accuracy and produce crop maps across the globe.
