David Buttler finished his PhD in 2003 at the Georgia Institute of Technology. He is working in the Informatics group at LLNL. His research interests are in information management systems for distributed data. The main challenges he is working with are information discovery, update monitoring, and source selection.

Dr. Buttler earned a B.Sc. in Computer Science from the University of Alberta in 1998, and he obtained his B.S. in Mathematics from Andrews University in 1995.



He is a member of ACM and SIGMOD


David works on these projects: Rapid Exploitation and Analysis of Documents; relevance-based information retrieval; knowledge-based coreference resolution.
