Research

Prof. Wu is one of the founders of the TIMBER project under development at the University of Michigan, a high performance native XML database system capable of operating at large scale, through use of a carefully designed tree algebra and judicious use of novel access methods and optimizations techniques. Her research in the Timber project focused on XML data storage, query processing and optimization, especially cost-based query optimization.

Prof. Wu's recent research at Indiana University involves algebra for XML queries, normalization, indexing and the security of XML data repositories. She is leading the research project on Access Control for XML (ACCESS) at Indiana University, focusing on developing a framework for flexible access constraint specification, representation and efficient enforcement. Prof. Wu is also involved in research related to data integration, data mining, and knowledge discovery.
