Research interests

  • Human-climate interaction, with special focus on the development during the last 10000 years and with a regional focus on the Eastern Mediterranean and South America
  • Palaeoenvironmental reconstruction as a basis for modeling future climate development
  • environmental reconstruction based on sedimentary analyses, radiocarbon dating and faunal assemblages
  • carbon cycle and hydrological cycle, groundwater renewal
