Gil joined Intel in 1994 as a software engineer and transitioned to the labs the following year. Beginning in 2000, Gil developed the processor extensions (known as Intel VT-x) for virtualizing the Intel 64 instruction-set architecture; he remains the lead architect of that technology. Since that time, Gil has continued to lead and make substantial contributions to successive changes to the Intel 64 system architecture. This work has included the development of numerous new features, including new methods for address translation, memory protection, context management, and signaling.
Before joining Intel, Gil was on the faculty of the Georgia Institute of Technology for six years. He earned a bachelor's degree in mathematics and psycholinguistics from Brown University, and a master's degree and Ph.D. in computer science from Cornell University. He holds more than 180 U.S. patents, nearly all in the field of microprocessor architecture, with many additional patents pending.
