  • Research Interests

    His research area of interest is remote sensing and geospatial analysis applications in precision agriculture and natural resource management. Amr utilizes multi-spectral and hyperspectral images acquired from satellite, airborne, and small Unmanned Aircraft Systems (sUAS) as well as lidar datasets. He uses machine learning algorithms, including deep learning networks (e.g., CNN, FCN, Deeplab) to analyze high spatial resolution sUAS images.

    At the application side, Amr leads and collaborates on multiple projects for agricultural crop yield modeling and phenotyping, vegetation biophysical and biogeochemical characteristics modeling, classifying submerged vegetation, and modeling water quality and soils parameters. He also used GIS to quantify forest ecosystem services.
