My research is currently focused on investigating how people share, evaluate and integrate diverse types of information in online communities, using the Answerbag question answering community as a primary testbed. This builds on my past research with collaborative digital library development projects, where scientists and professionals confronted many of the same challenges while attempting to integrate diverse collections of information, and the work of people with diverse expertise.
Some other projects I've worked on:
Alexandria Digital Earth Prototype (ADEPT), design and evaluation of a digital library of geospatial resources for undergraduate education (UCLA Department of Information Studies, 2000-2003)
NatureBib, a database of plants and animals found in Pacific Area national parks (U.S. National Park Service, 1998)
