I am a Research Staff Member in the IBM Research Austin Laboratory, where my current work revolves around high-performance computing for capital markets based on IBM POWER systems, with a current focus on distributed shared ledger (blockchain) technologies.
I rejoined IBM Research in 2014 after several years in the IBM POWER microprocessor development organization, where I contributed to the architecture, design, verification and modeling of the energy management infrastructure for IBM POWER7, POWER8 and POWER9 processors. Previous to that, I began my career at IBM Research here in the Austin lab, on projects spanning large server systems to small handheld systems, energy management, performance instrumentation, embedded systems and logic design.
In 2016 I was honored to be elevated to the grade of IEEE Senior member.
In 2015 I was honored to be named an IBM Master Inventor.
