Dr. Ezzat has a long history of accomplishment in the technology/industry as well as in University Academia. Dr. Ezzat has been an Adjunct Professor, Computer Science Department at Santa Clara University teaching graduate-level courses for the last 20+ years as well as at the Computer Science Department at San Jose State University teaching undergraduate-level courses for the last 2+ years. Dr. Ezzat believes that teaching is very rewarding profession as the reward can be very visible when you see your students excel and progress in their career.

In addition, Dr. Ezzat held senior executive positions for the last 15+ years including VP, Data Infrastructure at eBay, VP and Fellow at Yahoo!, Chief Technology and Fellow at HP Cloud Division, and Sr. VP Engineering and CTO in two technology start-ups (Velosel, Earlier at Oracle (Sr. Director & Architect), he architected and implemented the Oracle buffer cache to deal with SMP scalability and to provide better buffer management support to SQL runtime. This work resulted in providing unparalleled SMP scalability in the database market. Dr. Ezzat invented the LLRU algorithm (patent and an award) that was used in Oracle 7.3. Earlier at Cray Research (Section Manager & Architect), he led the NUMA T3D OS section. He has a patent on support multiple virtual page size to optimize performance in massive parallel processing NUMA platform. He delivered the T3D OS solution; T3D was one of the early commercial MPP NUMA platforms in the industry. After completing his Ph.D., he worked at Bell Labs Research (Member of Technical Staff), and won Arno Penzias (Head of Bell Labs Research and a Nobel Prize winner) award for his NEST (NEtworked workSTation) contributions. NEST supported unique model for processor sharing while maintaining autonomy and privacy; NEST was used internally at Bell Labs Research.

Dr. Ezzat has many publications, patents, inventions that are recognized at the industry-level, technology awards, and has chaired sessions in technical conferences. Dr. Ezzat received his Ph.D. in Computer Science, University of New Hampshire.
