Research Profile

I graduated from the Department of Aerospace Engineering (AE), Cairo University (CU) in Giza, Egypt. Then, I decided to utilize and develop my skills and started my research career by getting a M.Sc. degree in the field of numerical weather and climate modeling while working for the National Authority for Remote Sensing and Space Sciences (NARSS) in Cairo, Egypt. This exercise has more than prepared me for a Ph.D. degree from the Department of Earth and Planetary Sciences (EPS), Johns Hopkins University (JHU) in Baltimore, Maryland, USA. I have been working as a Research Scientist and a member of the Hydroclimate Research Group (HCRG). The overarching purpose of the group is to advance understanding of hydroclimate dynamics and of the manner in which hydroclimatic processes interact with ecological and human systems. In the process, we aim to develop tools for improved monitoring and prediction of regional atmospheric processes, landscape hydrology, and, in collaboration with many wonderful colleagues, coupled climate/environment/human systems relevant to human health, food and water security, and preservation of biodiversity.
