I was VP Engineering at Numenta from 2005 to 2014. I am currently VP Research at Numenta.
From 1999 through May 2005, I worked at YesVideo, a startup that made it easy for people to finally access their precious memories through automated digital media authoring. Working with partners such as Kodak and Fujicolor Services, we have created technology and services that allow inexpensive indexing and conversion of home videos to CD and DVD. YesVideo continues to thrive today. The service is available in over 30,000 stores in the US and Internationally.
In 1997, I co-founded ePlanet along with Meg Withgott and John Levy. It was a spin-off from Interval Research and created the first consumer application using computer vision. It was like Kinect, but 10 years earlier. Unfortunately it was several years ahead of its time. A more detailed description of our product and technology is here.
From 1993 to 1997, I was a researcher at Interval Research founded by Paul Allen and David Liddle. It was a very fun place to work, and encouraged big thinking. Among other projects (see ePlanet above), I was involved in creating what I think is the first working DVR. It was focused on recording TV news programs and automatically indexing them to online news articles. The main patent on that invention is here . That patent has become somewhat notorious in later Paul Allen lawsuits (actions I have no control over, by the way).
From 1991 to 1993 I was a post-doctoral guest researcher at Siemens Central Research in Munich. I developed a real-time computer vision based hand-tracker on very slow hardware. We got a fair amount of notoriety for that, including a spot on a national German prime-time news program. A video of that is here and here is a paper describing the work.
