John Keith Magali joins the TIMEleSS project!

John Keith MagaliJohn Keith Magali is a post-doc for the TIMEleSS project at the Université de Lille since September 2021.

After undergraduate studies in the Philippines he joined the International Center for Theoretical Physics in Trieste for a post-graduate diploma, followed by a PhD at the Université de Lyon. He is interested in inversion techniques of seismic data and how seismic data can be used as a constrain for geodynamics.

In TIMEleSS, John Keith will be in charge of studying the effect of mineral microstructures on elastic wave propagation and upscaling mineral physics knowledge to the scale of seismic observations.

Welcome!

Ernst-von-Rebeur-Paschwitz-Preis for Tine Thomas

Ernst-von-Rebeur-Paschwitz-Preis for Tine ThomasTIMEleSS PI Tine Thomas received the Ernst-von-Rebeur-Paschwitz-Preis from the Deutschen Geophysikalischen Gesellschaft in 2020 for her sustained excellence in science. The medal was awarded in 2020 with a virtual celebration ceremony in 2021.

Ernst von Rebeur-Paschwitz was an astronomer, geodesist and geophysicist, famous for his work on horizontal pendulums to record long-distance earthquakes. He also proposed to create an international network of seismological stations and this idea led to the founding of the International Seismological Association.

Since 2004, the DGG honors outstanding scientific achievements in the field of geophysics with the Ernst von Rebeur Paschwitz Prize. The target group are researchers from Germany or abroad who are in the middle or advanced stages of their careers, with an award every 2 to 4 years.

 

Frederica Rochira presents her work at EGU

Frederica Rochira at EGU 2019 in Vienna

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.

Jeffrey Gay joins the TIMEleSS project

Jeffrey GayJeffrey 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.

Estelle Ledoux joins the TIMEleSS project

Estelle LedouxEstelle 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 RochiraFederica 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.
