Related Professional Experience

  • Research consultant for Ayres-Sowell Associates and the Energy Simulation Group at Lawrence Berkeley Labs. June 1988 - present. Involved in design and implementation of SPARK, an object-oriented continuous simulation language. Major accomplishments: developed an optimization strategy for decomposing a system of equations into independently soluble subsystems.
  • Programmer. Various software companies. July 1981 - August 1986. Highlights: Designed and implemented PsyChart, a CAD tool for mechanical engineers, regarded by its distributor as an outstanding program for its longevity and maintainability (on the market for over fifteen years); implemented graphics drivers for Auto CAD; designed and implemented pre-Windows graphical user interfaces for DOS; implemented RSA-based encryption software for PC security.
