Post-doc in Lyon (Global seismology)
LGLTPE, CNRS, ENS and University of Lyon
We've got two years of funding for a post-doc in Lyon on global seismology. The successful applicant will be involved in the SEISGLOB project, http://geologie.ens-lyon.fr/seisglob/, a research program funded by the French "Agence Nationale de la Recherche" for years 2012-2015, whose goal is to develop improved S-wave tomographic models of the Earth's mantle. The first task of the post-doc will be to built a global whole mantle isotropic model combining all our data, potentially including the interface topographies. This involve the development of an inversion code able to combine various global datasets. Most of these datasets, including surface wave fundamental and higher mode dispersion and attenuation curves, long period body-wave travel-time measurements, body-waves reflected and converted at the 410 and 660-km discontinuities, have been built by members of the SEISGLOB team and are already available. Other datasets include available normal modes measurements from the literature.
A second task of the post-doc is to exploit several very large earthquakes which have occured in the last years, in order to complete available measurements with our own database of structure coefficients (which can be considered as secondary observables between seismograms and the 3D Earth structure) and quality factor estimates. This new dataset will be used simultaneously with surface wave, and/or body wave data to invert for a global Earth velocity and density model and to constraint a 1D model for mantle attenuation.
The post-doc will be supervised by Eric Debayle, Yanick Ricard and Sophie Lambotte . The inversion part wil be done in Lyon under supervision of Eric Debayle and Yanick Ricard. The observational part will be supervised by Sophie Lambotte from the university of Strasbourg. The post-doc will be done in Lyon at the "Laboratoire de Géologie de Lyon : Terre, Planètes et Environnements" . However, as most of the observational expertise is in Strasbourg, the post-doc is expected to spend few months in Strasbourg.
We are looking for somebody who has already some experience in seismology and that will be able to ponder the resolution of the different observations and their uncertainties. Applicants must have, or expect to obtain before the end of 2012, a PhD degree in geophysics, with a strong seismology component. They are requested to send a full CV (including the name and email address of at least two academic referees), a list of publication, and personal statement outlining how this research and training program will benefit from their past experience, and impact their career aspirations, to Eric Debayle (Eric.Debayle@ens-lyon.fr), Yanick Ricard (firstname.lastname@example.org) and Sophie Lambotte (email@example.com).
