I am a computer programmer with over 30 years of experience in human-computer interfaces, scientific and information visualization, and programming languages.
I'm currently the UI Architect at SQLstream, where I have been working on web applications such as the SQL end-user programming environment StreamLab, its visualization component s-Dashboard, and the Google Maps-based interface to s-Transport.
Over the past ten years I have been working, at least part-time, on a sabbatical research project: an experimental visual programming language and environment called Thyrd. Thyrd is implemented using Poet, an object-oriented extension to Tcl/Tk I've been working on sporadically since 1997. Both Thyrd and Poet have been released as open source. The best presentation on Thyrd so far is the talk I gave at the Emerging Languages Camp at OSCON 2010.
I was a Sr. Systems Architect for the Automated Molecular Imaging Group at The Scripps Research Institute half-time for two years, with the other half of my time spent working on Thyrd. Before that, I was the IT Director for the Neurosciences Institute for 11 years. Prior to that I was one of the founding members of the scientific visualization lab at the San Diego Supercomputer Center. Way back in the 1980's I ported Dungeon Master to the Amiga for FTL Games. I also worked in two labs at UCSD: the Quantitative Morphology Lab with Robert B. Livingston and the Cognitive Science Lab with Donald Norman. My complete curriculum vitae can be found here.
Throughout my career I have also served as a teacher, most recently for UCSD Extension. A page about the courses I've written and taught is here. The full course notes for each of the courses are provided.
My research interests include visual and end-user programming, scientific visualization, and biologically-inspired computing (evolutionary programming, artificial life, agent-based systems, neural networks, etc.). I'm inspired by systems like Self, Squeak, Boxer, and, strangely enough, Befunge.
