Work Experience


2003 — Present Consultant, Unisys Corporation

Unisys provides Mainframe and large-scale Windows server hardware and consulting services.

I have been leading a project at Unisys to integrate five Server optimization products and to define a single user interface for the suite of products. The project requires the cooperation of five different engineering groups as well as members of marketing and engineering management. The initial design phase of this project is just being completed and internal Unisys engineers will begin the development phase in the next few months.


2000 — 2002 Chief Technology Officer, Multi-Dimensional Imaging

MDI designs and develops advanced CT scanning equipment and provides technology services for HealthView full-body imaging centers. I was the corporate manager of a major MDI development project and led a team of over 40 engineers and scientists from various disciplines in the process of designing a next generation CT / Pet Scanner for use in the battlefield and non-military clinics. In addition I created a model of the enterprise processes of the clinical (HealthView) and technical (MDI) businesses in order to unify the data management needs for patient information, clinical study data, technical research data, product data management. and business systems.

My responsibilities included development and implementation of enterprise management processes; team building; communication between management, users, technology team, customers and vendors; implementation of technology policy; managing technology budget; hands-on project management; and proposal writing.

In developing these enterprise management processes specifically for MDI and HealthView, I used a combination of several enterprise and information modeling methodologies, project management tools and presentation software. I communicated effectively with members of the technical teams because I have a strong technical background in structured analysis methods, IDEF, UML, Oracle table definitions, and programming.


1984 - 2000 General Manager, Ontek Corporation

Ontek invented and designed formal methods and built knowledge-based information systems that were applied to large-scale data management and database integration problems for the aerospace industry and governmental agencies. The same formal methods were applied to developing enterprise architectures and related strategic planning activities.

One major requirement of the knowledge-based system was the ability to represent "document" as an entity. This requirement drove the theoretical team into several areas of research including classification theory and systematics, both of which eventually became the fundamental foci of the team’s efforts. I assumed responsibility for researching document classification systems including: LOC, Dewey Decimal, and Ranganathan’s Colon Classification, and how the metadata of MARC records was structured and used. I interviewed cataloguers at the UC Irvine Library and examined their use of LOC and MARC records, particularly how they made borderline subject classification decisions.

My responsibilities included enterprise process analysis and modeling, technical program management for large government contracts, leadership of local and off shore technical teams, interface with vendors and customers, web design, database design and programming, systems analysis, standards development and user interface design. As general manager I was responsible for resolution of any problems that arose between members of the staff and between the company and customers or vendors.

Following is a partial list of Ontek customers and my responsibilities:

IEEE/Department of Transportation, Web-based Data Registry - Chief Designer

Lockheed Martin, Technical strategic planning, enterprise architecture. — Analyst, Trainer

U.S. Air Force, Three major data modeling projects. - Program Manager, Designer

Ontek was the prime contractor on major R&D projects for the Air Force Manufacturing Technologies Directorate. I was the program manager for three of these projects and was responsible for project status reporting, management and technical presentations and technology transfer. I was also a member of the Ontek technical team. These project totaled over $15M in government and industry funding.

Aluminum Company of America, Information architecture. - Designer, Analyst

1986 - 1993 Research Consultant, Apple Computer

The Vivarium project was an Apple Research project headed by Senior Research Fellow Alan Kay. Alan Kay asked me to join the small research team based on my technical, education and music background. I explored the application of computers and programming to education.

I invented and constructed several large-scale physical human - computer interfaces (hardware and software), and designed activities to teach young children principles of programming.

I taught programming to teachers and children, built several computer-based music systems, and published a comprehensive Apple research paper on the Vivarium project, "Children, Computers and Programming".


1983 — 1984 President, Edgework, Inc

I founded Edgework, Inc. as an outgrowth of The Binary Tree, a computer learning center I founded in 1980. Edgework was the software development and product entity for software and courseware I developed at the center. During that time I collaborated with Steve Gibson of Gibson Research on educational software products that utilized his "light pen" for the Apple II computer. Steve Gibson also created a light pen for the Atari computer and Atari awarded me two contracts for educational software using the Atari light pen. I wrote a book of activities for students and teachers based on the children’s programming language Logo. Prentice Hall published "Apple Logo Activities" in 1984.


1980 — 1984 Founder / Director, The Binary Tree

The Binary Tree was a one of the first computer learning centers to open just as the first Apple II Computers were coming into the world. The center served children and adults in a pleasant, attractive environment that didn’t feel like a computer lab. The center offered classes, computer time and a summer computer camp program for children. The camp provided computer classes in the morning and snorkel diving and beach activities in the afternoon. The Binary Tree was a model for other centers that opened in the following years.


1971 — 1978 Co-Founder - Director, Tyna Elementary School

Tyna was a private elementary school stressing academic excellence in a supportive environment. I was the co-director with my wife, designed the math, science and music curricula and taught those subjects. I invented and built various teaching aids and manipulative materials. Tyna was a model alternative school known for its innovation and success with a spectrum of students from those with learning disabilities to highly achieving children of university professors.


1970 —1971 Teacher, UCI Farm School

The Farm School is an alternative school run by UCI. I taught science and math in a very loose and open environment.


1968 — 1970 Teacher, The Children’s Center

The Children’s center was a private elementary school in Tenafly, New Jersey, utilizing advanced, experimental educational technology and innovative teaching techniques. I taught a range of subjects to 3rd and 4th graders.


1966 — 1968 Technician, Operator, Ford Aeronutronics

Ford Aeronutronics was an aerospace R&D company. I was an electronics research technician and later became a supervisor of computer operations; responsible for payroll, labor reports and research computing.

1964 — 1966 Programmer, CEIR, Inc.

CEIR was a computer service bureau.. I was an IBM 7094 operator and programmer.


1961 — 1964 Programmer, System Development Corporation

SDC is an R&D company that primarily designs and builds simulations for the Air Defense Command and NORAD. I was an operator and later programmer for of one of IBM’s first large-scale computers, the ANFS-Q7. The Q7 was the fundamental computer used by the SAGE system, which was the nation’s air defense system in the 1950’s and ‘60s. I learned machine language programming, assembler, Fortran, and an early higher level language called JOVIAL.

I am an amateur musician and have applied my musical knowledge and ability to many work situations. My informal teachers have been highly trained academics and professionals in a variety of specific fields of study. My knowledge and ability have been tested extensively in professional and academic settings.

I have hands on experience with all MS Office applications, MS Project, Visio, Photoshop, Windows, and Unix/Linux operating systems.
