Research Profile

From the beginning of my educational journey, I recognized that I couldn't be just an operational person. I feel that I have all the required skills for an excellent researcher. This feeling grows with me and was continuously supported by my family, friends, teachers, and advisors. After my graduation from the Department of Aerospace Engineering (AE), Cairo University (CU) in Giza, Egypt, I decided not to work as a maintenance engineer in some airlines/company and I should utilize and develop my experience and research skills. Then, I started my research career by getting M.Sc. degree in the field of numerical weather and climate modeling. This exercise has more than prepared me for a Ph.D. degree. In my work, I have patience and the ability to master difficult problems. Therefore, I am always eager to move forward in my research career. I am very interested in the challenging tasks that lay ahead of me utilizing my excellent computer skills and proficiency in many operating systems, programming languages, and visualization software.

I have been working as Research Associate for the National Authority for Remote Sensing and Space Sciences (NARSS) in Cairo, Egypt. This made me involved in several projects on meteorological modeling, satellite data processing and visualization, and utilization of remote sensing technology to enhance/improve numerical weather modeling for Egypt. At NARSS, I also developed my experience in High Performance Computing (HPC). Currently, I am an Assistant Research Scientist and a member of The Hydroclimate Research Group (HCRG) in the Department of Earth and Planetary Sciences (EPS), Johns Hopkins University (JHU) in Baltimore, Maryland, USA. 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.

  • R Package HiClimR: A tool for Hierarchical Climate Regionalization applicable to any correlation-based clustering. It adds several features and a new clustering method (called, regional linkage) to hierarchical clustering in R (hclust function in stats library): data regridding, coarsening spatial resolution, geographic masking, data filtering by mean and/or variance thresholds, data preprocessing (detrending, standardization, and PCA), faster correlation function, different clustering methods, hybrid hierarchical clustering, multi-variate clustering (MVC), cluster validation, and visualization of region maps. Badr et. al (2015) describes the regionalization algorithms and data processing tools included in the package and presents a demonstration application in which the package is used to regionalize Africa on the basis of interannual precipitation variability.
