Research Interests

Thematic:

  • Quaternary landscape evolution of (hyper)arid coastal deserts
  • Interaction between fluvial, aeolian, and marine processes and analysis of complex geo-archives
  • Texture and spectral signatures of surfaces, weathering intensity and pedogenesis for morphostratigraphy in deserts

Methodic:

  • Remote sensing & GIS analyses
    (foci: geomorphologic mapping, UAV/UAS ("drone") surveys and photogrammetric processing, geomorphometry, multispectral satellite imagery, InSAR)
  • Cosmogenic nuclide dating
    (focus: Be-10 exposure dating)
  • Sedimentologic-pedological analyses

Regional:

  • Atacama Desert, North Chile
  • Skeleton Coast, Northwest Namibia
