We are looking for a post-doctoral research assistant to carry out physical modelling of thermomechanical processes taking place during the development of a subduction megathrust from its initiation to the establishment of a thermal steady-state. The project is broken down into two phases each expected to be 12 months in length. Ideally, but depending on background and motivation, the same person would carry out the two phases of the work, but it is also possible that two different people could undertake the two different phases of work. The goal of the first phase of work is to gain a first-order understanding of how the thermal structure in the plate overlying the subduction thrust develops towards a steady state, such as for example, what determines the lithospheric thickness. Calculations will be carried out using an existing numerical code. The goal of the second phase is to predict surface deformation and compare predictions with existing geodetic and/or seismic observations. The work will be carried out in the framework of a multi-disciplinary project on the Lesser Antilles subduction zone, coordinated by the volcanologic and seismologic observatory of Martinique, which is part of Institut de Physique du Globe de Paris. The PDRA will work under the direction of three permanent researchers: Steve Tait and Jean-Bernard de Chabalier at IPGP and Harsha Bhat at nearby Ecole Normale Supérieure.
The postdoc will develop state of the art large deformation finite element models for thermo-mechanical coupling.
Fracture Mechanics, Seismology, Computational Earthquake Source Mechanics
The post doctoral candidate would be based at the Laboratoire de Géologie (UMR 8538) at Ecole Normale Supérieure. Founded in 1880, the LG ENS is a joint research unit between the CNRS and ENS-PSL. Built on a long tradition in Earth and Environmental Sciences, it houses research that covers a wide field - Geology, Geodesy, Geomorphology, Geodynamics, Marine Geophysics, Geomechanics, Hydrogeology, Mineralogy, Seismology and Tectonics - which makes it a privileged place for exchanges at thematic borders.
