Bio: Professor Ludäscher's current interests include information integration (model-based/semantic mediation), especially of scientific data, and management of semistructured data (XML) database languages (active, deductive, object-oriented). Under his direction, researchers at SDSC's KBIS Lab (see bio) conduct research in Data & Knowledge Engineering to support the management and integration of scientific data. Scientific data management often requires a combination of traditional database technology and knowledge representation techniques. Main areas of research include: data modeling, knowledge representation, and query processing for model-based mediation (a.k.a. semantic mediation), scientific databases and workflows, and knowledge-based digital libraries and archives.

Research:

• Knowledge-based information systems
• information integration (model-based/semantic mediation) esp. of scientific data
• management of semistructured data (XML)
• database languages (active, deductive, object-oriented), query evaluation
• database theory
