Research

My research interests are in the fields of database and information systems, including data integration and sharing, data warehouses, data cleansing, data privacy, and information management on the Web. The following are several database projects I am working on.

Current Projects

• ASTERIX: Mike Carey and I are starting this project on Active, Scalable, Transactional Enterprise Repository for Information in XML. It's a new effort to develop a scalable semistructured information management system, based on XML and XQuery technologies, targeting very large shared-nothing compute clusters.
• FLAMINGO: A project on data cleaning.
• TASTIER: A joint research project with Tsinghua University on efficient auto-complete and type-ahead search on large data sets. .

• The Family Reunification Project. The goal of this project was to develop techniques to help people find their loved ones during or after a disaster.
• The Raccoon Project on Data Integration and Sharing. I started this project several years ago, and it's in its final stage. I still have some ongoing research related to this project. But compared to the first two projects, this one is less active.
• Data sets of the history of data objects collected from 6 web sites in 1.5 years..
