I am a computer scientist.

My professional interests are in the areas of video processing, machine learning, computer vision, and optimization. I am passionate about creating cool technology that can be productized. This is harder than it sounds, particularly if you insist on "cool technology".

Currently I work at Numenta, a startup developing a new type of computer memory system modeled after the human neocortex.

Until late 1999, I worked at ePlanet, a company I founded. We successfully shipped the first consumer computer vision product.

From 1999 through May 2005, I worked at YesVideo, a startup that is making 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 conversion of home videos to CD and DVD. The service is available in over 20,000 stores in the US and Japan.

At various points in my career I have worked on video indexing, real time people tracking, probabilistic networks, modeling human visual attention, and neural networks.
