Dr. Fleischer is a Research Staff Member in the VLSI Design Department at the IBM Thomas J. Watson Research Center. He received his A.B. degree in physics from Harvard University in 1981, and the M.S. and Ph.D. degrees in electrical engineering from Stanford University in 1987 and 1989, respectively. He joined the IBM Research Division in 1989 to do BiCMOS circuit design. From 1989 to 1992 he worked on BiCMOS SRAM and communications circuits. Since 1992, he has worked on microprocessor circuit design. Dr. Fleischer was a member of the floating-point team for the z900 microprocessor, and the lead circuit designer for the floating point units in the z990, POWER6, and BlueGene/Q microprocessors. At their announcement in Fall 2012, BlueGene/Q systems held top positions in the Top500, Graph500 and Green500 lists. His most recent work has been on methodology and tools to increase the productivity of logic and circuit design teams, exploratory architectures for new workloads, and the modeling and measurement of circuit variability.
Dr. Fleischer received two IBM Outstanding Technical Achievement Awards, for his work on the G7 (z990) microprocessor and for the BlueGene/Q Product. He has 36 issued and 9 pending patents.
