When there is a major environmental disruption such as a natural disaster or war, it is not only the technical infrastructure that needs to be repaired but also the human infrastructure. I am currently studying collaboration resilience-the extent to which people continue to work and socialize despite such a disruption. In this project we are examining the role that information technology plays in helping people repair their human infrastructure. We are focusing on the use of Web 2.0 technologies: blogs, wikis, social networking sites, video-sharing, and others that people use to be resilient in their work and lives during an environmental disruption.
