Essam Mansour

Postdoctoral Fellows


Since November 2009, I have been a Research Fellow in the Division of Mathematical and Computer Sciences and Engineering at King Abdullah University of Science and Technology (KAUST) since November 2009. I am contributing to research activities of the KAUST InfoCloud Research Group including leading a research project aiming at developing an elastic database system for processing very large strings based on the cloud infrastructure. This system is to support scientific data management, as a data-intensive application.

Prior to joining KAUST, I was a Research Associate at the School of Information Technology at the International University in Germany.

I received my Ph.D. in Computer Science from the Dublin Institute of Technology (DIT), Ireland. I graduated from Cairo University, Egypt in 2003 with a M.Sc. degree in Information Systems. I also hold a first class undergraduate degree in Information Systems from the same university.

Research Interests

My research interests span the areas of Databases and Information management with focus on:
  • Cloud Computing: Cloud Data Analytics - Elastic Scaleout Algorithms, Cost-Effective Management.
  • Parallel Systems: Cache-Efficient Algorithms - Load Balancing, Job Scheduling in HPC and Cloud Clusters.
  • String Processing: Suffix Trees - Sequence Indexing, Large-scale String Matching, String Query Optimization.
  • Mobile Computing: Context-Aware Query Management - Energy-Aware Algorithm.
