Professional experience

  • Information Systems Specialist, SLAC National Accelerator Laboratory, 1996 – present
    Main focus: extremely large-scale high-performance data access for scientific experiments. Responsible for the design and development of the Scalla/xrootd distributed data access system. Design and develop high-performance interfaces to the HPSS Mass Storage System. Design and develop high-speed network based data movement tools (e.g. bbcp)
  • Senior Systems Analyst, Cornell University, 1978-1996
    Designed and led the development effort for the initial HPSS Name Service which received a US patent. Designed and developed SideCar, a distributed authentication mechanism. Was the technical coordinator for Cornell’s Project Mandarin, a client/server widely adopted self-service student information system. Devised algorithms using multi-threading and vectorization to parallelize complex queries and data base transactions.
