Yuqing (Melanie) Wu

Faculty Title

Assistant Professor of Informatics

Research Statement

Prof. Wu was one of the founders of the TIMBER project 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 covers XML data storage, XML indexing, query processing, query optimization, query parsing and rewriting, and focuses on cost-based query optimization of XML queries. She is also involved in research related to data mining, Web data integration, and data extraction. Here, she is part of the Dbgroup.
