Professional Positions:
1999-Present Senior Consultant, Point&Click Solutions, Woburn MA
1987-1999 Programmer, GTE Internetworking [BBN Technologies], Cambridge MA
1985-1987 Senior Member Technical Staff, Palladian Software, Cambridge MA

1981-1983 Programmer, Biology & Astronomy Departments, Indiana Univ.

Professional Responsibilities and Projects:
Employed at Point&Click Solutions, a software consulting group located in Woburn Mass. Extensive work in the building of object-oriented Java and Lisp systems and user interfaces, editors, GUIs and GUI-building tools; ASP, XML/XSL and Servlet-based client/server systems; design and implementation of innovative visual user-interfaces and other GUIs; implementation of human-modeling systems; implementation and design of large, robust distributed systems; the re-implementation/extension of large-scale "legacy" systems (especially the extension of Lisp systems into a distributed Java-based environment); and early work in Genetic Programming.

Extensive object-oriented and distributed programming in JAVA, VBScript/ASP, XSL/XML, Tcl/Tk, JSP, various Lisp Systems, (Allegro Lisp, Lucid Lisp, CLIM and CLOS, Symbolics LispMachines), HTML/CGI, JavaScript, and PERL programming on Unix/Linux, Windows/NT, and Symbolics platforms.

Previous major projects have included:
• Designer and primary implementer on LIJOS , a Lisp Implementation of the Java ObjectStream.

• Co-designer and primary implementer on OMAR , a Lisp-based system for the development of state-of-the-art human performance models. Responsible for re-implementation of OMAR as Java-based distributed system.
• Participated in building of GUI components for ARGUS, a user-interface front end for a large-scale, distributed database of signals. Involved in design and implementation of VIA a web-based, distributed re-implementation of the ARGUS system.
• Co-designer and primary implementer of NSDD an HTML/webpage-based authoring/editing environment for the generation of indices into a large acoustic signal database.
• Participated in design and implementation of PRISM, an acoustic-network modeling system. Co-designer and primary implementer of a Java re-implementation of PRISM.
• Designer and developer of MIRAGE, a CLIM-based editor for building gadget-oriented Graphical User Interfaces.
• Designed and developed graphics-based user interfaces for: Air Force's OASYS system, a system for development for large testbed systems. NASA's RECORS system, a fault-finder pilot aiding system.
• The Navy's Capability Assessment Expert System [CASES] program, DARPA's Object-oriented Modeling Development Environment [OOMDE] and Planning Initiative [PE] projects.
• NASA's Information Management [IM] project.
• AMP's resource allocation program
• NASA's MAPLIST experiment. Developed mouse-driven system for the manipulation and editing of computer-scanned and CADCAM generated images of commercial aircraft approach-plates for use in an experiment concerning data utilization by the members of a working flight-deck crew.
• Primary developer of BRAHMS, BBN's Rule Based Human Modeling System. BRAHMS was used as the basis for:
  • The Air Force's Automation Impact Research Testbed [AIRT] project which models the behavior of a crew working in the Air Force's MCE radar air-traffic control system.
  • HIP, an extension of the AIRT project which involved allowing a human to interact directly with the other (simulated) crew-members via touch-screens, voice-understanding and speech-generation systems.
  • NASA's modeling of Space Station telerobotic manipulation system.

Previous employment history involved building user-interfaces, text manipulation and formatting systems, user-display systems and general system maintenance at Palladian software. At Texas Instruments primary projects including pilot-assisting expert systems; D/Dedalus, an interactive Dashboard editor; and various other systems developed for and using Symbolics LispMachines and the TI Explorer system.

Work in the Biology Department at Indiana University involved building and maintaining library/bibliography systems and a general system for the modeling of RNA-folding for use in a genetics laboratory and a data entry and reduction program for use in a population biology experiments. While in the Astronomy Department the work dealt with the design and implementation of a numeric modeling system as part of a project modeling the behavior and evolution of planetary rings.
