QCRI is one of the few serious research places in the Middle East and on track to be one for the key research centers worldwide. The opportunity of being part of this growing effort is the major attraction.

Research Focus at QCRI

Ihab’s research focus at QCRI is Data Analytics, in particular, data quality issues, information extraction, and probabilistic processing of uncertain data.

Previous Experience

Ihab Ilyas is an Associate Professor of Computer Science at the University of Waterloo and VP research at Primal. He received his PhD in computer science from Purdue University, West Lafayette in 2004. He holds BS and MS degrees in computer science from Alexandria University, Egypt. He spent two summers with IBM Almaden Research Center and he is currently an IBM CAS faculty fellow since January 2006. His main research is in the area of database systems, with special interest in top-k and rank-aware query processing, managing uncertain and probabilistic databases, self-managing databases, indexing techniques, and spatial databases.
