Nathan’s master’s thesis research focused, in part, on soil quality assessment through reflectance spectroscopy applications in the Avdat area. This project was summarized in the article “Using reflectance spectroscopy for detecting land-use effects on soil quality in drylands,” which was published in 2020 in the high-ranking journal Soil & Tillage Research. Following his successful studies, which included a stellar grade point average and a strong publication record, Nathan enrolled in the combined track Ph.D. program in 2019. As part of his doctoral research, Nathan used machine-learning techniques for analyzing terrestrial and airborne hyperspectral data in the context of soil quality in drylands. This methodological synergy is innovative and requires specialization in remote sensing with high computational and statistical skills. In his work, Nathan expanded the research area by focusing on the quantitative evaluation of the success (or failure) of phosphate mine restoration in the Zin region, using airborne imaging spectroscopy data. Nathan was the lead author of two additional papers in this study area. The first, entitled “Soil quality index for assessing phosphate mining restoration in a hyper-arid environment,” was published in 2021 in the high-ranking journal Ecological Indicators. The second article, which was recently published (2022), is entitled “Predicting land-use effects on soil quality in an arid environment using imaging spectroscopy.” This article was published in one of the highest-ranking remote sensing journals, the ISPRS Journal of Photogrammetry and Remote Sensing.
