I am with the Inclusive Design Research Centre at OCAD University, and am the main programmer for the GnomeShell magnifier. I am also tangled up with the W3C and the WAI-ARIA effort.
Other projects I've worked on:
- dojo toolkit - adding ARIA, keyboard a11y, and automated UI testing.
- Fluid project - flexible user interface design.
- Web-4-All - a smart-card based AT/workstation configuration system.
- audio look and feel for Swing.
