Current Position:

Scientific Staff - Geospatial Datamanagement, Collaborative Research Center 806

Research interests:

My main research interests are in the folowing topics:

  • GIS and Spatial Analysis
  • Environmental Modelling
  • Web based GeoInformation Systems (WebGIS)
  • Spatio-Temporal Data Modeling
  • Open Science (Open Data, Open Source, Open Access)
  • Spatial Data Infrastructures (SDI)
  • Research Data Management
  • Climate Change

I work on this topics with a focus on paleoenvironmental and archaeological questions.
