Forschungszentrum Jülich: Multiscale Geophysics of soil-plant systems

Forschungszentrum Jülich: Hydrogeophysics


Professour in Hydrogeophysics. This professorship is a joint appointment of the Forschungszentrum Jülich and the University of Cologne.

We develop and apply hydrogeophysical methods to enhance the characterization of the critical zone including aquifers, peatlands, permafrost soils and agricultural fields. One of our main foci is to enhance the resolution of small-scale heterogeneity related to the soil-plant system.

Research Topics:

  • Hydrogeophysics, Hydrology and Permafrost Geophysics
  • GPR, GPR Full-waveform Inversion
  • Electromagnetic Wave Propagation
  • Geophysical Modeling, Imaging and Inversion techniques
  • Wetlands/Peatlands Geophysics, Environmental and Engineering Geophysics

News and Links:

  • Mastertopic projects: High-frequency GPR full-waveform inversion to characterize soil structures inside a lysimeter
