Welcome to my home page.  I hold a dual-culture faculty position at the University of Hawaii that's at the intersection of Information & Computer Sciences and Library & Information Science.  I'm interested in how people integrate diverse types of knowledge, from collections of diverse documents to the work of people with different kinds of expertise.

I study information integration in interdisciplinary scientific collaborations as a Co-Investigator with the NASA Astrobiology Institute at UH, and in social computing environments with the Answerbag question answering community.
