We've begun work on a new project called "Helping Hands: Computer Support for Community-Maintained Artifacts of Lasting Value. The idea is to make it easy for communities to create and maintain valuable resources like wikipedia. Of course, part of our solution is recommenders -- in this case to help people find the parts of the artifact they will be most able and willing to imporove.

I helped with meta-reviews for IUI 2006. Some of the papers look great!

I'm a meta-reviewer for CHI 2006. A great group of papers, as usual.

Research Interests

My research focus is on collaborative systems that support human interaction through computer systems. My career goal is to understand how to develop and apply computer technology to the problems of human organizations.

One of the biggest such problems is getting the right information to the right people. The Internet has democratized the publishing process. Now, anyone who wants can publish anything they want, just by creating a Web site. We humans are hopelessly overmatched by the increasing volumes of information that are published. Collaborative filtering is a technology that enables us to all work together to sift through the millions of documents on any topic to find those that are most appropriate for each of us. Collaborative filtering works by learning which kinds of documents each of us likes, and finding other people who share out interests.

Across our entire research program, our goal is to understand how computers can be used to help people process information more efficiently, and work together better.

I am currently involved in several research projects to explore these topics.
