The 2020 TIMEleSS Annual Meeting was held online on 8-9 September 2020. 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, Angelo Pisconti, Christine Thomas), and the Deutsche GeoForschungsZentrum, Potsdam (Sergio Speziale) met for two half-days to discuss current advances and future plans.
The first day was dedicated to progress report by the PhD students. The second day followed by a scientific presentation by our guest Morvarid Saki and discussions on the geophysical implications of the results.
Despite the 2020 conditions, the TIMEleSS project is nicely moving forward. Students are reaching a stage when they fully interact with each other. The PIs can’t wait for next year with results and publications!
The one day symposium has presentations from local and international speakers who all came to Münster for a day of science and discussions. The workshop was organized by TIMEleSS PI C. Thomas.
TIMEleSS PI S. Merkel gave a presentation entitled Phase transitions in the lowermost mantle : Effect on microstructures and seismic reflections. TIMEleSS students F. Rochira and M. Krug presented posters on their most recent works.
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!

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 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, mineral physics) to present the results of her works and discuss their implications for understanding the dynamics of mantles, on Earth and other planetary bodies.
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!
Matthias Krug and Frederica Rochira gave presentation in front of their institute in Münster.
Matthias presented his work on Jan 8th and Frederica on Jan 21st. These presentations were an opportunity for the students to display their works in front of their colleagues, get feedback, and new ideas for their project.
Estelle Ledoux and Jeff Gay presented they current work at the PhD student days for the UMET lab in Lille. The symposium is organized yearly in January.
This one-day meeting is an opportunity to discover the work of current PhD students and the evolution of research in the lab. It is an opportunity for exchanges between students and researchers, exchange ideas, and build strong future collaborations.
Federica Rochira and Matthias Krug presented posters at the Deep Earth Mini Symposium in Münster. The symposium was organized by TIMEleSS PI Tine Thomas.

She received a Bachelor degree in Geology from the Université de Caen and a Master degree in Earth, Environment and Planetary sciences at the Université de Orléans. She is interested in minerals, their microstructures, and how they can be induced by deformation. After working on the deformation of natural plutonic rocks under the Cyclades islands, she is now looking into the Earth’s interior.
Her PhD project is funded by the Université de Lille and TIMEleSS. He role within TIMEleSS will concern phase transitions in mantle minerals.
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.
Matthias Krug is a PhD student in the mineralogy group at WWU Münster since April 2018.
After finishing his Bachelor’s in Geosciences he continued with a Master’s in Geomaterials, both in Göttingen. He is interested in the composition of the earth’s interior and how different minerals and their phase transitions determine the behavior of the whole system.
His contribution to the project will be to investigate microstructures and textures induced by phase transition in basaltic crust using high-pressure synchrotron experiments.
