Training on Polycrystal Properties Modeling, Oct 2019

TIMEleSS Training on Polycrystal Properties Modeling

This weeks, students from the TIMEleSS project and our special guests are in Lille to learn about polycrystalline properties. The course is focused on calculating elastic properties and seismic wave propagation features in a polycrystal, textured or not. We also spend some time trying to model texture development in a deformed polycrystalline aggregate thanks to VPSC simulations. The participants from the TIMEleSS project, Jeffrey Gay (Lille), Estelle Ledoux (Lille), Matthias Krug (Münster), Federica Rochira (Münster), are delighted to host our very special guests, Tommaso Mandolini (Lille), Ilya Kupenko (Münster), Angelo Pisconti (Münster), Morvarid Saki (Münster), and Lea Pennacchioni (GFZ) for the week. All should dream of Euler angles and 3D-rotations by the end of the week!

We are hiring!

We are hiring! The TIMEleSS project is looking for a post-doctoral fellow. The position is available for 1 year and extendable. The position is attached to the Earth and Planetary Materials group the Unité Matériaux et Transformations, at the Université de Lille, France, with strong collaborations with the Institute for Geophysics at the University of Münster. The candidate should have a strong background in deep Earth seismology and/or wave propagation in complex media and/or mineral physics and will be in charge of connecting mineral physics knowledge of phase transformations and microstructures in the Earth’s mantle to potential observations of seismic reflections and scattering. Details on the position, conditions, and requirements can be found in the following document.

Colloque de la Sfµ 2019

Estelle Ledoux presents her work at the Colloque de la Sfµ 2019

The Colloque de la Sfµ is the meeting of the French microscopy society. It is held annually and mostly focuses on electron microscopy techniques. Estelle Ledoux, PhD student partially financed by TIMEleSS, presented her results on EBSD analyzes of plastically deformed polycrystalline MgO. The work is a result of a collaboration between the group at the University of Lille and that of L. Miyagi at the University of Utah. The results of the work will be useful for the TIMEleSS project for addressing properties of the Earth’s lower mantle.
