Welcome to my home page.  I'm a Professor of Information & Computer Sciences (ICS) and Library & Information Science (LIS), and a graduate faculty member of the Interdisciplinary PhD Program in Communication & Information Sciences (CIS), which encompasses four units and three colleges across the University of Hawaiʻi at Mānoa

I'm interested in how people integrate diverse types of knowledge, from document collections to the work of people with different kinds of expertise.  I study interdisciplinary scientific collaborations with the NASA Astrobiology Institute, and social Q&A communities--for details, see my Research page.  I'm also helping develop Learnamic, a site where homeschooling parents and children can discover and share learning resources.  If you're interested in any of these projects or programs, feel free to contact me.
