Areas of Research:

Biographical Sketch:

One-page statements of research and teaching respectively.

Projects:

• The TSIMMIS project (The Stanford IBM Manager of Multiple Information Sources) which provides a new approach to accessing, gathering and browsing heterogeneous, semistructured information information from disparate sources.
• The WHIPS project (WareHousing Project at Stanford) which is developing algorithms for incrementally maintaining views in the data warehouse. Other research thrusts range from automatically detecting changes to the data stored in the sources, to integrating new data with existing information in the warehouse, to organizing the contents of the warehouse in order to optimize multi-dimensional analysis and data mining, for example.
• Joint research project with Stanford's Knowledge System Laboratory (KSL) group developing a formal framework for achieving interoperation among heterogeneous information sources. This work is a continuation of my thesis work with Prof. McLeod from the CS Dept. at USC.
• Various technology transfers of TSIMMIS code to government agencies.
