Ruby Lee is professor of electrical engineering at Princeton University, since September, 1998.  Previously, she was chief architect, responsible for processor, multimedia and security architectures, at Hewlett-Packard, California, where she has worked for  17 years as a practicing computer architect (1981-1998).  She was a founding architect of the HP PA-RISC architecture, and instrumental in the evolution of PA-RISC architecture and systems over several generations, for product lines including mission-critical business servers, high-performance technical workstations and real-time manufacturing controllers.  She was also the lead system and logic designer for the first CMOS PA-RISC microprocessor and later, manager for microprocessor design.  She was chief architect of the cross-functional Multimedia Architecture team, and designed the MAX-1 and MAX-2 multimedia acceleration extensions for PA-RISC processors.  This resulted in the industry’s first software MPEG player product, which utilized MAX-1 to achieve real-time, high fidelity MPEG-1 video decoding on  low-end HP workstations in January 1994, three years before the introduction of  Pentium chips with MMX.  Lee also co-led one of the Intel-HP architecture teams, in the definition of the IA-64 architecture, which includes advanced architectural features for exploiting Instruction Level Parallelism.  She was also chief architect of the cross-divisional Security Architecture team for e-commerce and extended enterprise security,  and dealt with issues ranging from cryptography acceleration to enterprise security architecture to strategic roadmaps.  She also served as consulting associate professor (1989-1995), and as consulting professor (1995-1998) of Electrical Engineering at Stanford University.

Lee has an A.B., with distinction, from Cornell University (1973), a M.S. in Computer Science and Computer Engineering (1975) and a Ph.D. in Electrical Engineering from Stanford University (1980).
She has served as program chair for conferences (e.g. HotChips) and editorial board member for technical publications (e.g. IEEE Micro and HP Journal).  She holds 18 U.S. patents on processor architecture, pipeline design, cache hints, and multimedia architecture, algorithms and arithmetic.  Memberships include IEEE, ACM, Phi Beta Kappa, and Alpha Lambda Delta.
