I have been developing ontologies, algorithms, and programming tools to support reasoning about distributed data arising from many data mining and control applications. Together with Chris Bailey-Kellogg, Ken Yip, Xingang Huang, and Ivan Ordonez, I have developed the Spatial Aggregation Language (SAL) and have applied it to applications such as distributed control optimization, weather data analysis, and spatio-temporal diffusion-reaction pattern analysis. SAL 1.2, a MATLAB-like rapid prototyping tool (C++ libs, interpretive environment) for scientific data mining and control applications, is available to the research community and has been used by a group of Stanford students for class projects in CS329 that I taught in Fall 1998.

• SAL: papers, applications, software, and documentation
• Automated phase-space analysis and control synthesis
• A maglev nonlinear control prototype
• Intelligent simulation (Project INSIGHT at Ohio State)
