In the frame of the DONUTS project (Numerical tools for interpretation and processing of geophysical data for geothermal and underground energy reservoirs), the RING team is currently seeking two postdoctoral researchers to be selected before April 1st:

- Postdoc 1 concerns the seismic upscaling and downscaling of fractured media. This work will be carried out in close collaboration with the Geosciences department of MINES ParisTech. The position is available for one year, starting as soon as possible, with a possible extension to a second year. More information...

- Postdoc 2 concerns the implementation and benchmarking of potential field response on realistic geomodels. The position is available for 6 months, starting as soon as possible, with a possible extension to a full year. More information...
