Development Projects: 1966-1998

Explorations in CollaborationOMOLANIM.GIF (58744 bytes)

CO-PI, Organizational Memory and Organizational Learning (OMOL) Project

1997-2000 Center for LifeLong Learning & Design, University of Colorado

Co-managed an effort to explore group memory support and computer mediation of collaborative learning through a variety of investigations. Below is information about some of the short-term explorations. Continuing projects are described under Projects, Readings, and WebGuide:

bulletAstroQuest: mock-up of a game for exploring the solar system and constructing knowledge using the web.
bulletSimRocket: a simulation of rocket launches used to support collaborative learning by 6th graders about data analysis.
bulletLocations: mock-up of an interface to an organizational memory of weather station locations around the world and their identification codes.
bulletMedGuide: mock-up of a version of WebGuide for collaborative learning by medical students.
bulletNorth Rim/Lake Valley Trails Committee: organizational memory of a community campaign for well-conceived open space trails.
bulletWebInquiry: a threaded discussion on the question, "Does the Web Support Student Inquiry?"
bulletLatent Semantic Analysis: click here for general info on LSI/LSA.

WebNet Design Environment

a design environment for computer network design, including a collection of relevant information sources, a design simulation with critiquing and a repository of shared simulation components.

bulletWebNet: a design environment for computer network (LAN) design.
bulletThe Elmo Project: a collaborative information environment for computer network (LAN) management.

CO-MANAGER, USEFUL & USABLE SOFTWARE PROJECT

1996-1997 Center for LifeLong Learning & Design, University of Colorado

Co-managed a group of post-docs, visiting researchers, graduate students and a four-person senior project engaged in research and prototype development to support the design and maintenance of computer local area networks (LANs).

Corporate Information Environment (CIE)

a collaboration environment to support ISO 9000 documentation management and total quality management.

SOFTWARE DESIGNER

1996 Black Labs, Boulder, Colorado

Developed a prototype system for presentation to venture capital sources. The system was designed to support companies seeking ISO 9000 certification to develop documentation of all procedures through a collaborative process involving multiple personal and group perspectives on evolving document drafts.

bulletWorld Wide Web
bullethuman-computer interaction
bulletImplementation of software, stressing user testing.
bulletInstallation, training, support, maintenance, enhancements.
bulletTailoring of system to personal preferences and professional roles.

OptoNet Holographic Stabilizer

DIRECTOR OF SOFTWARE R&D

1993-1996 Owen Research Inc., Boulder, CO

Automated stabilization of holographic optics equipment for research in space. Project research included visual programming of a neural network and alternative feedback algorithm to supervise controls of an adaptive optics system that stabilizes a laser interferometer for crystal growth research in space. Software feedback system in Labview tested in zero-g on KC-135 flights at NASA.

NASA Crew Simulation

The CREW system predicts psychological factors of astronauts based on previous missions, personal characteristics and a statistical model

DIRECTOR OF SOFTWARE R&D

1993-1996 Owen Research Inc., Boulder, CO

Developed case-based reasoning system for use by NASA in astronaut crew selection. AI programming using time-series statistical modeling, results of small group behavioral studies, dynamic memory and fuzzy logic in LISP/CLOS and FOXPRO on Macintosh and Windows computers. Installed system at Johnson Space Center.

Hermes Design Environment

The LUNAR HABITAT DESIGN ENVIRONMENT supports innovative design with computational hypermedia including a proprietary perspectives mechanism and an end-user programming language.

DOCTORAL STUDENT & RESEARCH ASSISTANT

1989-1993 University of Colorado, Boulder, CO

Developed technologies for object-oriented design environment. A series of research projects sponsored by Colorado Advanced Software Institute focused on intelligent hypermedia system, mechanism for personal perspectives, and end-user programming language for design rationale navigation that included sophisticated query language with inferencing. The custom OODBMS incorporated virtual copying for efficient inheritance of object versions. Interviewed and videotaped engineers in NASA subcontractor. The resulting code is now being used for NASA.

Dissertation research explored computer support for interpretation processes of professionals, including implementation of a software design environment for lunar habitat designers using innovative AI technologies.
