PROFESSIONAL EXPERIENCE
  University of California, Riverside
    Distributed Real-Time Systems Laboratory 
    Designing, implementing using Java and C++, and evaluating
    distributed protocols for sharing-aware component composition,
    load prediction and hot-spot alleviation, management of
    large-scale distributed real-time applications, and data
    dissemination in peer-to-peer systems. Leading the development of
    the Synergy distributed stream processing middleware; supervising
    other student research projects now using the platform.

  IBM Research
    T.J. Watson Research Center, Hawthorne, NY, Summer 2007
    As a member of the advanced enterprise middleware group, designed,
    implemented in Java, evaluated, and documented a replication
    middleware for distributed, multi-tier, server architectures.
    Prepared a patent for the middleware's efficient, distributed
    strong consistency protocol.  Quantified the server replication
    and data partitioning performance benefits, as well as the
    consistency overhead, using the TPC-W transactional web commerce
    benchmark.

  Intel Research
    Pittsburgh, PA, Summer 2006
    As a member of the research team of the reliable email project,
    designed, implemented in C++, and documented an event-driven 
    software prototype of a collaborative spam filter that employs a 
    distributed protocol to defend against sybil attacks.  

  Hewlett-Packard
    Enterprise Storage & Servers, Colorado Springs, CO, Summer 2005
    As a member of the replication team of an upcoming product of
    HP's grid storage portfolio, designed, implemented in C++, and
    documented a logging mechanism used for asynchronous replication in a
    distributed disk array.  

  University of Patras, Greece
    High Performance Information Systems Laboratory 
    Designed and implemented in C a protocol for dynamic memory
    page migration across the nodes of a Software Distributed Shared
    Memory System, as part of an inter-departmental diploma thesis.  
    Dynamic page migration improves performance by increasing locality and 
    adaptability, while remaining transparent to the application programmer.

  FGAN e.V.
    Bonn, Germany, Summer 2000
    Analyzed the H.323 protocol family, used for multimedia
    applications (VoIP) in packet switched networks, and summarized
    the results in a technical report, including detailed protocol
    description and performance evaluation of applications under IPv6
    in Solaris.
