PhD 10 : High resolution imaging of transport processes with GPR full-waveform inversion

This position has been filled ! Please look at our other PhD positions offers !

The Institute of Bio- and Geosciences – Agrosphere (IBG-3) conducts research to improve our understanding of biogeochemical and hydrological processes in terrestrial systems. Specific studies focus on environmental controls on biogeochemical cycling of elements, the analysis of exchange processes and nutrient dynamics in the soil-plant-atmosphere continuum. A combination of experiments, modelling and innovative observation technologies is used to bridge the gap between model, process and management scale. Its research contributes to the sustainable and resource-conserving use of soils and water and to the quantification of the effect of climate and land use change on terrestrial ecosystems. We offer a competent and interdisciplinary working environment, as well as an excellent framework in the areas of experiments and modelling.

We are looking to recruit a :

PhD Student with a degree in geophysics, physics, hydrogeology, computational geoscience or related natural sciences

Your Job:

In the IBG-3, advanced modeling and inversion algorithms are developed and applied for a wide range of hydrogeophysical studies using ElectroMagnetic Induction (EMI) and Ground Penetrating Radar (GPR) systems. This PhD position is part of the EU funded project “ENIGMA”, a European training Network for “In situ imaGing of dynaMic processes in heterogeneous subsurfAce environments”. The primary objective of this project is to extend and apply existing full-waveform GPR data processing algorithms for the time-lapse characterization of transport processes. The project offers the unique opportunity to connect novel processing and inversion techniques to real data in a state-of-the-art computational environment.

Your Profile:

  • Master degree in geophysics, physics, hydrogeology, computational geoscience, or related natural sciences with a good final grade
  • (Hydro)Geophysical field work experience, preferably with GPR
  • Advanced knowledge of numerical methods
  • Experience in (matlab) programming
  • Strong English writing and communication skills

Our Offer:

  • working in an interdisciplinary environment as well as excellent facilities for hydrogeophysical research and numerical simulation and inversion studies
  • Opportunities to being part of the national and international scientific community
  • within the ENIGMA training network, several workshops are organized and several other PhD Student work on the development of innovative methods for imaging process dynamics in subsurface hydrosystems
  • PhD students are encouraged to attend international conferences and two research visits of several months abroad with cooperating ENIGMA partners are planned

starting date: 01.01.2017

  • Payment of the PhD fellow will be based on 75% TVöD EG 13
  • International, interdisciplinary working environment on an attractive research campus, ideally situated between the cities of Cologne, Düsseldorf, and Aachen
  • Exciting working environment on an attractive research campus, ideally situated between the cities of Cologne, Düsseldorf, and Aachen
  • Limited for 3 years
  • Salary and social benefits in conformity with the provisions of the Collective Agreement for the Civil Service (TVöD).
