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!

TIMEleSS Annual Meeting

The TIMEleSS Annual Meeting was held at the Jugendherberge in Aachen, Germany, on 23-24 July 2019. Members from the Université de Lille (Julien Chantel, Jeffrey Gay, Estelle Ledoux, Sébastien Merkel), the Westfälische Wilhelms-Universität, Münster (Matthias Krug, Federica Rochira, Morvarid Saki, Christine Thomas), and the Deutsche GeoForschungsZentrum, Potsdam (Sergio Speziale) met for two days to discuss current advances and future plans. The first day was dedicated to progress report by the PhD students followed by a scientific presentation by our guest Morvarid Saki. Projects members discussed potential interactions and plans for the next year during the second day. The meeting a was great opportunity to highlight the current achievements of the project and to focus the work that remains. We now[…]

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.

Frederica Rochira at EGU 2019 in Vienna

Frederica Rochira presents her work at EGU

Frederica Rochira was at the EGU General Assembly 2019 in Vienna. EGU brings together geoscientists to one meeting covering all disciplines of the Earth, planetary and space sciences. The meeting is held yearly in Vienna, Austria, and, in 2019, it was attended by 16,273 scientists from 113 countries. Frederica Rochira presented her works entitled Detecting structures in the mid mantle using out-of-plane signals in the multidisciplinary session Dynamics of the mantle in the Earth and planetary bodies: from magma oceans to the present day. The session, co-organized by TIMEleSS members, included four oral presentations on Thursday as well as 12 PICO presentations early afternoon on Friday. The session was an opportunity for scientists of various fields of geosciences (seismology, geodynamics,[…]

Samples for experiments at PETRA III

Synchrotron beamtime for TIMEleSS

The TIMEleSS group is at the PETRA III synchrotron this week-end. Matthias Krug, Estelle Ledoux, Jeff Gay, Julien Chantel, Carmen Sanchez-Valle, Sébastien Merkel, and special guest Anastasiia Zadoia will be spending some time at P02.2… Two months of sample synthesis, polishing, coating, cutting, and 10 diamond anvil cells loaded. Nights will be shorts for the next four days. Let’s cross fingers, we need data for our next multigrain diffraction datathon!

Jeffrey Gay

Jeffrey Gay joins the TIMEleSS project

Jeffrey Gay is a PhD student in the Earth and Planetary Materials group at the Université de Lille since October 2018. He received a Bachelor degree in Geology from the Montana State University and a Master degree in Geophysics from the University of Utah in the United States. He is interested in deep Earth materials interactions, extreme conditions experiments, and the deformation properties of minerals. In his free time, he can be found snowboarding, climbing, and cycling. In the past, Jeffrey taught mineralogy and structural geology as a teaching at the University of Utah. His PhD project is funded by the TIMEleSS project. His role within TIMEleSS will concern phase transitions in mantle minerals.

Federica Rochira

Federica Rochira joins the TIMEleSS project

Federica Rochira is a PhD student in the seismology group at WWU Münster since March 2018. She received a Bachelor degree in Geology and a Master degree in Geophysics at the University of Bari in Italy. She is fascinated by the structure and composition of the Earth. After working on the Earth’s crust, she is now looking deeper into the mantle using a multidisciplinary approach that combines seismology, the most powerful tool “to see” the interior of the Earth, with mineral physics, the key to interpret seismic data. Her PhD project within TIMEleSS focuses on investigation of seismic signals from structures and discontinuities in the mid-mantle using array seismology method.
