Welcome!

This web site contains samples of the HCI-related experience I have had during my professional career, 1992–2004.

I have worked as a professional programmer since 1992. I am currently enrolled in the Master's program in Human-Computer Interaction at Carnegie Mellon University, taking two classes each semester while working full-time.

Each project in this site illustrates one or more of the following skills and interests:

• User-Interface Design: screens, icons, physical components, and other interactive tools enabling a person to both perceive and control information.
• Information Architecture: the design and development of an information-storage and -processing structure, including database relationships, object-oriented class hierarchies, APIs, and modular, reusable, programmable software components.
• End-to-End Design and Development, in which I both designed and built interactive, user-friendly tools.
• Documentation: information structuring and layout, intended for a printed document.
• Teaching or mentoring, in the workplace and the classroom.

To me, "human-computer interaction" encompasses all of those perspectives, and the ways in which they overlap:

• how information is structured in peoples' minds;
• how that information is represented inside the computer;
• how that information can be presented — on screen, in print, or in other physical media; and
• how people can then interact with that presentation to manipulate both the information and the real-life systems it represents.

I hope the projects presented here illustrate how those interests and skills have expressed themselves in my professional work over the past 12 years.

A note: I have worked on a number of projects which are relevant to HCI, but for which I am unable to obtain the documentation. Those projects are summarized, and are shown in italics at left. In addition, this site does not yet contain examples of the work I have done while at Carnegie Mellon; I will gladly provide samples of that work on request.
