Attending SEDI meeting in Zurich !
June 2022
I was invited to give a talk at the 40th anniversary of GEOSCOPE held at IPGP. You can find the recording of the talk here entitled “Mantle’s drapes: 30 years of global tomography”.
I was also invited by the AFPSVT (Association pour la formation des professeurs de SVT) where I talked about “Global tomography: Why? How? and what’s new?”
Fevrier 2022
I participated to the “Journées de la SFMC” giving a talk entitled “La tomographie sismique révèle la présence de manteau fondu sous les plaques tectoniques”
November 2021
We got a funding for a post-doc position about “The origin of earthquakes: combining seismic observations and analog experiments”. You can find a description of the project here. Please contact me if you are interested. Applications are due for April 1rst 2022 for starting on 1rst September 2022.
16th November I will be giving a seminar at ENS Paris on “Rotational motions and seismology” about our recent paper “Understanding Micropolar Theory in the Earth Sciences II: The Seismic Moment Tensor”.
Our paper “Understanding Micropolar Theory in the Earth Sciences II: The Seismic Moment Tensor” is accepted for publication in Pure and Applied Geophysics.
From 1rst and 5th November the LGL-TPE is organizing the 27th RST 2021 “Réunion des Sciences de la Terre”. We organize a session on the “Interdisciplinary approaches for studying the mantle” (T2.1 S. Rhône 3B) and a session on “Big Data” (T10.1 S. Saint Clair 1)
October 2021

Consider submitting an abstract to our EGU session “Mantle Structure and Evolution: Combining Seismological and Geodynamical Constraints Across Scales” (GD2.2/SM4.11).
Over the last few decades, seismologists have been able to illuminate the Earth’s interior and identified a number of mantle structures, including the lithosphere-asthenosphere boundary, a possible transition at about 1000 km depth, small scale heterogeneities in the transition zone and lowermost mantle (ULVZ, D"), plumes, stagnating slabs. While the origin of these structures is still debated, numerical simulations can help validate tomographic models and predict plausible scenarios. However, geodynamic models and tomographic images often investigate different physical parameters, and propose views of the mantle at separate scales. Combining information from both fields is therefore necessary to understand and link mantle processes across scales. We encourage contributions that can feed the dialogue between seismologists and geodynamicists.
Conveners: Simone Pilia, Stephanie Durand, Bernhard Schuberth, Benoit Tauzin, Martina Ulvrova
November 2019
Our paper “Kinetics and detectability of the bridgmanite to post-perovskite transformation in the Earth's D' layer” accepted in Nature Communications.
I spent one week visiting Prof. J. Jackson’s group at CalTech and I gave a seminar on “Global tomography: Why? How? What’s new? What is the future?”
October 2019
Interviewed on France Culture in “La méthode scientifique” about “Stormquakes” a GRL paper that came out this month from Fan et al. Can be listened there:
You were many to write me because you were not able to install SeisTomoPy from GutHub, the error was for downloading the “models.zip” file. It is now all fine, I changed the url.
June 2019
Starting a new position at LGL-TPE as CNRS researcher.
December 2018
Our paper “Constraints on D″ beneath the North Atlantic region from P and S traveltimes and amplitudes ” accepted in GJI.
I am a seismologist, focusing on global imaging of elastic, anisotropic and anelastic Earth’s mantle structures using surface waves, body waves and normal modes. Basically, the question I try to answer is what is the origin of the seismic heterogeneities in the Earth’s mantle and to do so we need to combine different information such as seismic velocities, anisotropy and attenuation.
You are curious, you want to know what is beneath your feet ? Have a look to our Python tool SeisTomoPy to investigate the interior of the Earth’s mantle.
