I have been at UBC since January 2001. I am currently an Assistant Professor teaching both graduates and undergraduates.

Before that I was in the Artificial Intelligence Center at SRI International in Menlo Park, California. While there I worked on the Digital Earth project and various computer vision research projects. The Digital Earth project was by far the broadest though; we dealt with computer graphics, goespatial localization, distributed data, and a real plan to change the world. We started with TerraVision, a sophisticated real-time geographical visualization system which we saw as a potential browser for any network-accessible geo-referenced content. In fact, This lead to the development of GeoVRML, a standard for georeferencing 3D models in VRML. We finally came to the conclusion that a real global digital earth needed the spatial equivalent of a search engine, so we set out to design it.  The GeoWeb was born of this need and is still a dream, thanks to some arbtrary actions of ICANN. Sadly the driving force behind SRI's whole Digital Earth project, Yvan Leclerc has since passed away. We've lost a great opportunity with the loss of his vision and energy.

Before SRI, I was a graduate student in the Centre for Intelligent Machines at McGill University. My PhD is in Computer Vision.
