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.

Forum "Enseigner les Géosciences", Lille, Octobre 2018

Lecture for high school teachers

One of the TIMEleSS PI’s gave a general lecture on Mantle Convection this week. The French geological society meeting (Réunion des Sciences de la Terre) was held in Lille between Oct 22 and Oct 26, 2018, and included a workshop on Teaching Earth Science in High Schools dedicated to high school teachers in Northern France. The workshop included a day of scientific presentations during which S. Merkel gave a class on Mantle Convection and a day of field trip. The workshop was also a nice and rare opportunity for high school teachers in Northern France to be in contact with international research in their region.

Federica Rochira and Estelle Ledoux having a discussion with Ed Garnero in Les Houches, October 2018

Two students of the TIMEleSS project at the Deep Earth School in Les Houches

Federica Rochira and Estelle Ledoux attended the Doctoral Training on Internal Earth in Les Houches during the last two weeks. The lecture topics included Earth magnetism, with Céline Guervilly and David Cébron, Mineralogy by Nadège Hilairet and James Badro, Mantle Dynamics by Clint Conrad and Maylis Landeau, and deep Earth Seismology by Ed Garnero and Pierre Boué. Xavier Le Pichon gave the introductory seminar, a rare opportunity to meet one of the fathers of plate tectonics! Two weeks of great opportunity for advanced classes and meeting world experts!

Estelle Ledoux

Estelle Ledoux joins the TIMEleSS project

Estelle Ledoux is a PhD student in the Earth and Planetary Materials group at the Université de Lille since May 2018. 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 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.

Matthias Krug joins the TIMEleSS project

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.

Opening for two PhD positions!

The TIMEleSS project is looking for 2 PhD student. Both students will investigate the link between microstructures, phase transitions and seismic structures in the Earth’s deep mantle using a combination of advanced diffraction methods at synchrotron sources and in-house experimental facilities. Both positions should start on March 1st, 2018, or whenever the position are filled. The first position will be based at the Institute for Mineralogy of the University of Münster (Germany) under the supervision of  Prof. Dr. Carmen Sanchez-Valle and will focus on materials relevant for deep subducted slabs. The second position will be based at the Unité Matériaux et Transformations of the University of Lille (France) under the supervision of Prof. Dr. Sébastien Merkel and will focus on[…]

The TIMEleSS project was selected!

Good news during the gray fall months of 2017: the TIMEleSS project has been selected! The TIMEleSS acronym stands for “Phase TransformatIons, MicrostructurEs, and their Seismic Signals from the Earth’s mantle”. We will receive a bilateral grant, from the ANR in France and the DFG in Germany, for a total sum of approximately 700 k€. The project includes salaries for 3 PhD students, 1 post-doc, undergraduate works, travel, consumables, and some equipment for our experiments. The project is led by Sébastien Merkel and Nadège Hilairet at the Université de Lille, Christine Thomas and Carmen Sanchez-Valle from the Westfälische Wilhelms-Universität, Münster, and Sergio Speziale from the Deutsche GeoForschungsZentrum, Potsdam. With the project, we aim at studying deep mantle discontinuities through a combined[…]
