Stéphanie Rossano is a professor at the University of Paris-Est Marne la Vallée. Her main research theme concerns the study of vitreous material structures and their evolution under the influence of various altering agents (time, water, microorganisms). To access the structural information she seeks, she uses methods of solid spectroscopy (X-ray absorption, Mössbauer, UV-Visible spectroscopy, etc.). She associates it with classical molecular dynamic simulations or ab initio calculations. More punctually, she leads research on complex materials of archaeological (bone, pigments, etc.) and geological interest (minerals containing chromium, etc.).
CNRS Research Director, in the Laboratoire de Géologie de l’Ecole normale supérieure (Paris). His main interests are metamorphic and experimental petrology, phase relations, fluid-rock interactions, and the characterisation and crystallochemistry of minerals, especially silicates and phosphates. He is in charge of the publication of the SFMC journal: European Journal of Mineralogy.
Anne-Marie is a CNRS director of research working in the Laboratoire de Géophysique Interne et Tectonophysique of Grenoble. Her research is based on fluid-rock interactions, and more precisely on mechanisms of deformation and fluid circulation in active fault zones, with implications for the seismic cycle. Her recent work mainly focussed on deformation and hydrothermal alteration of the Nojima fault (Kobe earthquake) and of the Chelungpu fault (Chi-Chi earthquake), through analysis of drill cores.

Anne-Line Auzende was awarded a Ph.D. by the University of Clermont-Ferrand in 2003. Anne-Line has worked on serpentine minerals in convergent settings, focussing on the microstructure and physical properties of serpentine minerals, with implications for the rheology of subduction zones. Anne-Line then used experimental petrology under extreme conditions during her post-doc at the Institut de Minéralogie, Physique des Matériaux et Cosmochimie(IMPMC, Paris), to better understand the composition and structure of the lower mantle. To do so, her approach focussed on studying the partitioning of elements between high-pressure phases. Anne-Line was appointed as a lecturer at University Paris Diderot, where she combines her research with teaching.
Researcher at the Institut de Recherche pour le Développement (IRD). His research work, conducted at the Institut de Minéralogie et Physique des Milieux condensés (Paris VI University), focus on the use of minerals to trace tropical climate alteration processes and geochemical cycles acting on the Earth’s surface. He uses spectroscopic tools to determine the individual characteristics of mineral categories, linked to the presence of specific defects. In parallel, he uses theoretical numerical tools to interpret spectroscopic measurements and to model the physico-chemical properties of these minerals.
Sylvain Bernard is a CNRS researcher at the LMCM-MNHN. His objective is to deepen the understanding of the geological cycle of organic carbon on the basis of a multidisciplinary approach at the interface between geochemistry, mineralogy and paleontology. During his PhD thesis defended in 2008 at the Laboratoire de Géologie de l’Ecole normale supérieure (Paris), the use of advanced techniques of spectromicroscopy has made it possible to highlight the preservation of signatures of living organisms within rocks that have undergone intense metamorphism. At the same time, he laid the foundations for an experimental approach to the fossilization of organic molecules. In postdoctoral studies at GFZ-Potsdam, he was interested in the processes of degradation of organic molecules linked to the formation of hydrocarbons. Today, his research aims to answer this fundamental question: how do organic molecules and biominerals evolve under complicated geological history?

The research of Delphine Charpentier is focussed on geochemical and mineralogical transformations during interactions between sedimentary rocks and fluids. Delphine has special interest for processes involving clay minerals, such as mass transfer and mineralogical reactions in fault zones and redox changes in iron-rich systems. Her approach combines high-resolution mineralogical studies and geochemical modelling techniques.
Valérie Chavagnac received a PhD in geochemistry in 1998 from the University of Bern (CH) and the University of Rennes 1 (FR), where she studied the behavior of the Sm-Nd isotope system during metamorphism. During her stay at MIT (USA), she continued working on the geochemical composition of archean rocks, more precisely the komatiites of the Barberton Greenstone Belt. She moved to the National Oceanographic Centre, Southampton (UK) in 2000 and changed her research activity to oceanic hydrothermal activity. Since 2007, she has been a CNRS researcher at the Laboratoire des Mécanismes et Transferts en Géologie in Toulouse. Her research interests are the chemical composition of hydrothermal fluids, especially those rich in hydrocarbon and hydrogen.
Stéphanie DUCHENE is a professor at Paul Sabatier University in Toulouse (France). Her research focuses on the determination of the kinetics of magmatic and metamorphic processes by radiochronology (Sm-Nd and Lu-hf in metamorphic garnet rocks), geovelocimetry (modelling of element diffusion in minerals) and analysis of crystal size distributions (plagioclase in basalt).
After a background in matter and radiation physics, Denis Testemale did his thesis at the Laboratory of Crystallography (CNRS, Genoble) on the structural description of supercritical aqueous solutions (molecular interactions, hydrogen bonding, ion pairing) using X-ray absorption and diffusion techniques. He continued these studies as part of his post-doctorates at ESRF and Adelaide University (Australia), and today, he focuses his studies on the transport of metals in hydrothermal fluids, using methods that take advantage of synchrotron radiation. He combines this research activity with the reception of users on the X FAME (INSU national instrument) absorption line at the ESRF.
