Research Interests

I consider myself an experimental computer scientist. I build software prototypes that explore cutting-edge software engineering technology and analyze that technology's behavior. The technologies that I am most interested in are the analysis and optimization of object-oriented languages, and software distribution.

Education

  • University of Wisconsin, Madison

    • All But Dissertation in Computer Science, April 1997.

    Recipient of the IBM Resident Study Fellowship.

  • Columbia University

    • M.S. in Computer Science, School of Engineering and Applied Science, May 1988.
    B.S. in Computer Science, School of General Studies, January, 1984.

    Experience

  • Research Staff Member
    IBM T.J. Watson Research Center 6/2000-present
    Continuting to extend the Jalapeño Adaptive Optimization System. See our paper in OOPSLA 2000.
    Exploring server support to provide on-the-fly software maintanence and configuration for pervasive devices.
  • Advisory Software Engineer,
    IBM T.J. Watson Research Center 5/97-5/2000
    Co-developed and patented methods for reducing, at the language level, the space overhead in object-oriented applications.
    Co-implemented this technology in JAX, a Java application extractor, that is available on alphaWorks.
    Led a project to evaluate different memory layouts for C++ objects. The results of which have determined the memory layout in IBM's Visual Age C++ compiler.
    Co-designed and co-implemented adaptive optimization system in the Jalapeño Java virtual machine.
  • Staff Software Engineer,
    IBM T.J. Watson Research Center, 5/94-5/97.
    Designed and implemented a prototype simulator that explored the dynamic properties of C++ applications. Used this prototype to evaluate different call graph construction allgorithms, to evaluate dead data member elimination algorithm, and to evaluate C++ memory layouts.
  • Senior Associate Software Engineer,
    IBM T.J. Watson Research Center, 8/92-4/94.
    Designed and implemented the code generation component of the IBM High Performance Fortran compiler. The compiler became a product offering on IBM's SP-2 distributed computers.
  • Associate Software Engineer,
    IBM T.J. Watson Research Center, 5/85-7/92.
    Co-designed and chief implementor of a tool that supports distributed software development in a heterogeneous computing environment that was integrated into a object-oriented software development environment, RPDE.
    Co-developed graph attribution as a specification paradigm and an evaluation algorithm for the attribution that generalizes attribute grammars from an underlying tree data structure to a directed acyclic graph.
    Explored limitations of object-oriented languages to support sophisticated software development.
