Professor of Physics @ ULille and Institut Universitaire de France, Project leader of the TimeMan Project
Trained as a materials scientist, Patrick Cordier has worked mostly in the field of mineral physics. His research interests are related to the mechanical properties of solids with a special focus on dislocation theory. Specialist of transmission electron microscopy he has pioneered the application of Large Angle Convergent Beam Electron diffraction to defect characterization in minerals and now Precession Electron Diffraction. Since 1995, he has, with his students, elucidated the slip systems and dislocations of most high-pressure phases of the Earth’s mantle. For that purpose, he has developed and performed high-pressure deformation experiments in the multianvil apparatus (mostly using the large-scale facilities of the Bayerisches Geoinstitut). These experiments have also been applied to materials science studies (silicon, silicon carbide, quasicrystals). Recently, he has developed with Philippe Carrez and PhD students a new approach of plastic deformation under extreme pressure based on multiscale modeling within the ERC funded RheoMan project (2012-2018). Patrick Cordier is President of the International Mineralogical Association (IMA). From May 2019 to Mai 2020: P. Cordier is invited professor at the Université Catholique de Louvain, Belgium. Patrick Cordier is Senior Member of the Institut Universitaire de France.
Professor of Physics @ ULille
Professor in the Physics Dpt of the University of Lille since 2015, Philippe Carrez is in charge of the numerical modelling of dislocations in mineral phases. His researches focus on the atomic structure of dislocation cores, on the dislocation mobility and on dislocation interactions at the mesoscale. Together with Patrick Cordier, he is involved in the recent development of a multi-scale model of plasticity for mantle minerals under pressure and temperature conditions relevant of the Earth interiors.
Lecturer @ ULille
Alexandre Mussi is lecturer in the IUT A Dpt of the University of Lille. He uses the transmission electron tomography technique on dislocations to characterize the fundamental plastic deformation mechanisms of minerals (such as olivine) deformed under mantle conditions, in relationship with numerical modeling. He also uses automated crystal orientation mapping in a transmission electron microscope to characterize plastic deformation mechanisms from complex dislocation microstructures
Lecturer @ ULille
Karine Gouriet is a lecturer in the Physics Dpt of the University of Lille. Her research interests cover the numerical modeling of deep Earth mineral plasticity. Karine‘s main responsibility in TimeMan project is to investigate the plasticity of mantle’s minerals like olivine, ferropericlase, bridgmanite,..., using dislocation dynamics.
Lecturer @ ULille
Pierre is a lecturer at the Physics Department of the University of Lille since 2016. After studying physics at the University of Rennes, he modelled the plastic deformation of metals at the atomic scale during his PhD in Poitiers, France. Then, during a first post-doc at the Karlsruhe Institute of Technology in Germany, he investigated the interplay between dislocations and functional properties in technologically relevant materials, such as the perovskites SrTiO3 and KNbO3. In 2012 he joined the RheoMan project and investigated the plastic deformation of bridgmanite, the most abundant mineral in the Earth's lower mantle. Over the years, Pierre also developped Atomsk, a code to produce data files for atomic-scale simulations.
Post-doctoral researcher @ ULille
After graduating (Master) in quantum physics at the Faculté des Sciences of Tunis (Tunisia), Sami Mahmoud has prepared his PhD at the Université de Montréal (Quebec, Canada) under the supervision of Prof. N. Mousseau. He defended his thesis entitled “Numerical study of point defects diffusion in nickel-based alloys” in May 2019. In TimeMan, Sami Mahmoud will use the activation-relaxation technique to model defects in minerals.
Chercheur qualifié FNRS @ UCLouvain
The overall objective of the research activity of Prof. Hosni Idrissi is a fundamental investigation of the physics of defects dynamics in different classes of inorganic materials including minerals, nanocrystalline metallic and metallic glass thin films, hybrid multilayers combining crystalline and amorphous systems as well as bulk coarse-grained metals and alloys involving twinning-induced-plasticity (TWIP) and transformation-induced-plasticity (TRIP). The core questions concern the competition or the synergy between the nanoscale elementary mechanisms, which ultimately control the strength and ductility of these materials. The overall research approach is based on the design and use of quantified new nanocharacterization tools including nanomechanical testing methods (lab-on-chip, nanoindentation, etc.) coupled with advanced transmission electron microscopy (TEM) techniques (aberration corrected high resolution TEM imaging and spectroscopy, electron tomography, orientation and nanostrain mapping in TEM, in-situ TEM nanomechanical testing, etc.) to unravel the mechanisms under interest.
Dominique (Nick) SCHRYVERS
Professor @ EMAT
Dominique (Nick) Schryvers is Full Professor at the research group Electron Microscopy for Materials Science (EMAT) of the Department of Physics of the University of Antwerp. His main research topic is the application of advanced transmission electron microscopy techniques to the study of phase transformations in alloys, more specifically in systems displaying martensitic transformations but also diffusional transformations and precipitation mechanisms. In recent years he got more involved in nanocrystalline metallic systems of different origin and in in-situ nanomechanical testing. He has also worked on photographic materials, historic materials, geo- and cosmological materials, composites, soft materials, etc.

Michaël Coulombier received the M.S. degree in degree in material science from UClouvain, Louvain-la-Neuve (Belgium) in 2006. He finished his PhD in 2012 under the supervision of Prof. Thomas Pardoen (iMMC) and Prof. Jean-Pierre Raskin (ICTEAM) developing a lab on-chip technique for nano-mechanical characterisation of thin films. Since then he has been a research assistant in iMMC involved in various projects dealing with material science, nanomechanical testing and tribology.
