I received my Ph.D. degree in electrical and computer engineering from the University of Texas at Austin. I was a member of the HPS Research Group at the University of Texas at Austin. Before that I worked as a researcher at Hyundai Motor Company Research Center between 1998-2000 to develop next-generation engine designs. I was an intern at Intel Corporation during the summers of 2002, 2003, 2004, and 2006, working on problems in computer architecture and hardware/software interaction. Research: My research interests include high-performance energy-efficient computer architectures, programmer-compiler-architecture interaction, low-power high-performance embedded processors, and compiler and hardware support for dynamic optimizations, virtual machines, and binary instrumentation.
