2018 October 31 3rd GEOTREF PhD defense

The third GEOTREF PhD has been defended by Viven Navelot at 2 pm, the 31st October 2018, in the Ecole Nationale Supérieure de Géologie de Nancy: Structural and petrophysical characterization of a geothermal system in a volcanic subduction arc context. Example of the Guadeloupe archipelago.


Geothermal systems located on active volcanic islands lying above subduction areas are increasingly being prospected and exploited as they represent significant, renewable and accessible energy resources with relatively low operating costs. The Basse-Terre Island in the Guadeloupe archipelago and more precisely the Vieux-Habitants area gathers several indicators allowing to suppose the occurrence of a high-temperature hydrothermal system.

2018 September 28 2nd GEOTREF PhD defense

The second GEOTREF PhD has been defended by Keurfon Luu on septembre 2018 at 2 pm, the 28th September, in the Ecole des Mines de Paris : Numerical optimization using stochastic evolutionary algorithms: application to seismic tomography inverse problems.


Seismic traveltime tomography is an ill-posed optimization problem due to the non-linear relationship between traveltime and velocity model. Besides, the solution is not unique as many models are able to explain the observed data. The non-linearity and non-uniqueness issues are typically addressed by using methods relying on Monte Carlo Markov Chain that thoroughly sample the model parameter space. However, these approaches cannot fully handle the computer resources provided by modern supercomputers.
