Research

Professional Interests

• High-performance Distributed, heterogeneous information systems and databases
• Middleware, WWW, Distributed Object Computing, Grid Plattforms
• Semantic interoperability, integration of applications and data sources
• Geo Information Systems, Spatial Databases and Data Warehouses

Current Projects

• BMBF GLOWA program: "Global Change and the Hydrologic Cycle"
  GLOWA Volta project, Cluster I: "Integration and Data Management Systems"
  Development of a GeoData Infrastructure (GDI) for a decision support system in the GLOWA Volta project

Finished Projects

• SkySynch
  Synchronisation of time in wireless sensor networks (tmoteSky)

• COBIDS (COmponent-Based Integration of Data and Services)
  Was set as a continuation of the OPALIS project. The system was extended with new features. The application domain was shifted from a pure geo-related context to other domains, e.g. life science and biological applications.

• eXtensible Database Adapter (XDA) (my PhD Project)
  CORBA/ODBMS integration framework

• DFG joint project "Interoperable Geoscientific Information systems (IOGIS)"
  Subproject "Open paleoecological information system (OPALIS)"
  Development of an open and extensible information system based on software components technology and providing integrated access to heterogeneous geoscientific data.

• DFG Collaborative Research Centre (SFB 350) "Interactions between and Modelling of Continental Geo-Processes"
  Subproject D4: "Object-oriented 3D/4D geo-information system"
