Research Scientist, Environmental Sciences and Engineering
Dr Lopez received his PhD in Environmental Science and Engineering from the King Abdullah University of Science and Technology. He has formed part of the Hydrology, Agriculture, and Land Observation research group since then, now as a research specialist. His dissertation focused on hydrological fluxes and stores in the MENA region, using Land Surface Modelling and Remote Sensing. His work provided a methodology to estimate agricultural water use at the national scale.
Dr Lopez’s main research focus encompasses the analysis of geospatial data including satellite images and climate data, as well as the application of computational hydrological models. His research has focused on the mapping of agricultural fields and estimation of crop water use at regional to national scale through cloud computing platforms.
