Leadership Skills

As Vice President, Customer Service, manages both custom software implementations and full-service offshore data conversion projects for Exegenix's clients. Also supports business development efforts.

As Vice President, Technology, helped guide the development of Exegenix data conversion software. Also provided input to marketing decisions.

As Manager, Toronto Solution Center, staffed and led Open Text's Toronto consulting group.

As Systems Integration Technical Coordinator for InfoDesign Corporation, provided technical guidance for projects run out of offices in Ottawa, Toronto and Washington. Consulting projects over eight years involved designing complete systems, allocating modules to programmers of both client and consulting companies, and managing their work.

Led team of four programmers in the design and implementation of a module for the Indiana University Computer Science Department database. Coordinated five teams during integration phase of project.

Communication Skills

Able to put computers in context: to clearly explain key business implications of technical decisions.

Worked with molecular biologists to design a 3D graphic protein-folding program. Developed smooth backbone and size/shading depth cues to allow visualization of complex protein molecules, simultaneously showing overall structure and local detail.

Worked with physically handicapped people and therapists to develop a graphical interface for controlling household robots. Invented 'Flat 3D' as a way to achieve the advantages of 3D with the simplicity of 2D. Have developed natural-language interfaces.

Technical Skills

SGML/XML consulting involves designing markup schemes for complex text databases while reengineering the corresponding business processes. The resulting database publishing systems allow multiple output media (paper, CD-ROM, Web) while simplifying editorial and publishing workflows.

Nearly twenty years structured-programming experience, including five years 2D and 3D graphic programming in C. Strong theoretical background in mathematics and computer science. Assisted with drawing layer of Microsoft Works for Macintosh.

As a result of my work with the Macintosh Toolbox and PC Smalltalk, I am practiced at developing event-driven graphical user interfaces.

My undergraduate and Master's work in programming-language design means that I am comfortable with all programming idioms, including object-oriented approaches such as C++ and Java.

Doctoral research involved the latest ideas in user-interface design and implementation. Systems integration work has involved developing systems that run on networked Unix, Windows, OS/2 and Macintosh platforms.
