Wael Bahaa-El-Din is a Technical Fellow in the Windows Core Operating Systems division.  He leads the Windows Engineering System & Services organization and drives major advances in the quality of Windows and its engineering.  His teams develop innovations throughout Windows to improve its end-to-end quality in areas such as performance, reliability, diagnosis, feedback, and application experience.  His teams also engineer Windows for worldwide markets, improve the Windows experience with service packs and updates, and build a world-class engineering system for developing software at the scale of Windows.

He joined Microsoft and the Windows organization in 1994. He built a world-class performance group of experts who guided development teams in engineering performance-competitive products and attaining scalability in large enterprises.  Over the past decade, he also has led company-wide quality initiatives and expanded his responsibilities to other areas of quality.  He has been instrumental in pioneering diagnostic and recovery initiatives, enhancing quality monitoring, focusing on fundamental customer satisfaction, and making deep improvements in product readiness for release.

Bahaa-El-Din has worked on the design, architecture, and performance analysis of operating systems, database systems, networking, server applications, client applications, compilers, tools, and hardware.  He has had an impact on the performance and the reliability of more 40 products at both Digital Equipment Corporation (DEC) and Microsoft.  His expertise in analysis techniques spans the spectrum of analytical modeling, queuing, measurements, prototyping, and simulation.

Prior to joining Microsoft, Bahaa-El-Din worked at DEC for seven years on database performance and scalability, which included operating system and hardware performance.  He was the top Consulting Engineer in the commercial performance area, and also influenced the design of new hardware systems to perform and scale well on database workloads.

Bahaa-El-Din also worked in academia before moving to the software industry. He earned his Ph.D. in computer science from Ohio State University in 1984 and M.S. from the University of Alexandria in 1979. During his academic career, he published numerous IEEE and ACM journal and conference articles on performance analysis, supervised graduate research, and taught courses in computer science, networking, and performance analysis.
