I currently am working on several projects.
Most of my work is part of the GroupLens Research Group. That work includes work on recommender systems, eliciting participation in onlne community, and general questions related to social computing.
I am also working as part of the RWJF-funded Interdisciplinary Research Leaders program as part of its Culture of Health focus. On that project I am designing technology support for research/community team collaboration.
I am working on other projects in conjunction with the U of M School of Public Health, including projects on HIV prevention and on nutrition databases.
