Sébastien Merkel is the French PI. He is a professor of physics at the Université de Lille. His research focuses on understanding the dynamics and formation of the deeper portions of the Earth. He performs experiments under the pressure and temperature of the Earth’s interior to study microstructures in polycrystals, their mechanical behaviour, and their relation to phase transformations. He then integrates the experimental results into polycrystal numerical models to understand wave propagation through complex microstructures and compare the results of these models to seismic observations. This work aims at understanding the dynamics and formation of the Earth’s mantle and inner core.

Christine Thomas is the German PI. She is Professor for Geophysics at the WWU Münster and her research focuses on deep Earth’s structure and processes. Mantle transition zone discontinuity structure, D” structure, seismic scattering and anisotropy in the deep Earth are among the topics studied. For this she and her group use mostly array seismic data and techniques to detect mantle structures and boundary layers in order to understand processes that generated these structures. Especially the connection of mineral physics and seismology are a large part of the research carried out in Münster seismology group.

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.
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.
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.
Jeffrey Gay is a PhD student in the Earth and Planetary Materials group at the Université de Lille since October 2018.
