PRESIDENT Michel GREGOIRE
Michel Grégoire is a CNRS director of research working in Toulouse in the “Géosciences Environnement Toulouse » (GET) laboratory. Michel is a petrologist interested in the origin and evolution of mantle, magmatic and metamorphic rocks with mafic and ultramafic composition, in continental and oceanic domains. To carry out his research, he uses optical and electron microscopy together with laser ablation ICP-MS.
VICE-PRESIDENTE Nathalie BOLFAN-CASANOVA
Nathalie BOLFAN-CASANOVA is a research director at the CNRS within the Experimental Petrology Team of the Magmas and Volcanoes Laboratory (Clermont-Ferrand). She is an experimentalist who synthesizes samples representing the deep Earth but also of other planets in order to study the incorporation of point defects, such as hydrogen or ferric iron. She is specialized in high-pressure techniques but has also participated in the use and/or development of various spectroscopic analysis methods (FTIR, Raman, XANES, ERDA).
VICE-PRESIDENT Fabrice GAILLARD
Fabrice Gaillard, senior researcher at CNRS, department of Earth Sciences at Orléans (ISTO): I am an experimentalist, specialized in high pressure high temperature methods, with consolidated background in chemical thermodynamics. My research activities tackle volatile species and magmatic systems on Earth and elsewhere: how it impacts on deep geodynamics via mantle/crust melting and how it affects surficial geochemistry via volcanic degassing.
SECRETAIRE GENERAL Marc BLANCHARD
Marc Blanchard is a CNRS director of research working in Toulouse in the “Géosciences Environnement Toulouse » (GET) laboratory. He has interest in processes controlling isotopic fractionation, in the crystal chemistry of mineral phases with environmental importance and in the crystal chemistry of volatiles in the mantle. To this end, Marc mainly uses molecular-scale modelling techniques and spectrosopy.
SECRETAIRE GENERAL ADJOINT Pierre LANARI
Pierre is assistant professor at the Institute of Geological Sciences (University of Bern), where he works in the field of metamorphic petrochronology. He has become an expert in both chemical and isotopic analyses using electron microprobe and Laser Ablation Inductively Coupled Plasma Mass Spectrometry. He has also developed a software solution (XMapTools) for quantitative micromapping analysis. Compositional mapping is combined with U-Th-Pb dating of accessory minerals to constrain the crystallisation kinetics and conditions of mineral formation and re-equilibration, especially in high-pressure and high-temperature rocks.

TRESORIER ADJOINT Benoît DUBACQ
Benoît Dubacq is a CNRS researcher working at the Institut des Sciences de la Terre de Paris. He studies fluid-rock interactions in metamorphic rocks.

MEMBRES DU CONSEIL
CONSEILLERS SCIENTIFIQUES (mandat 2021-2024)
Emilie Bruand is a CNRS researcher at the laboratory « Magmas et Volcans » at the University of Clermont-Ferrand (France). Her research focuses on exploiting chemical signatures locked within Rare Earth Elements- bearing minerals to help understand large-scale Earth processes and geodynamics. Over the past years, she developed new petrological tools using in-situ analytical techniques (microprobe, ionprobe, LA-(MC)-ICPMS)to unravel magmatic and metamorphic evolution across geological time. Her research interests include, crustal evolution, the early earth, high grade metamorphic rocks, igneous and metamorphic petrology, oxygen and neodymium isotopes.
Associate professor at Sorbonne Université and at the Institut de minéralogie, de physique des matériaux et de cosmochimie. He is studying the mineralogical and geochemical processes governing the elements behaviour in the environment in order to answer diverse scientific questions : the mechanisms of rare metals concentration, the dynamics of soil organic matter and more broadly the processes forming regoliths. He is coupling multi-scale analytical techniques, from the bulk sample to the molecular scale.
CNRS Researcher at Institute of Earth Sciences (CNRS, Grenoble). His main interests are fluid-rock interactions in hydrothermal systems (serpentinization) and in metamorphic rocks (eclogitization). He combines petrological studies with the use of experimental and numerical tools to determine the kinetics and the mineralogical processes involved in natural environments.
Jean-Marc MONTEL is an engineer who graduated from École nationale supérieure de géologiein 1982 and obtained a Ph.D. from the Institut national polytechnique de Lorrainein 1987 for his experimental geochemistry work supervised by Michel Pichavant and Alain Weisbrod. He worked in Clermont-Ferrand as a CNRS researcher from 1988 to 1999 at the Laboratoire Magmas et Volcansin the experimental petrology research team. His work then was focussed on partial melting of the continental crust. In 1994, he established the U-Th-Pb dating method with electron microprobe. He moved to Université Paul Sabatier of Toulouse in 1999 where he was awarded a professorship. There he mostly worked on synthesising monazite-based ceramics for long-term nuclear waste storage. He was assistant director then director of the LMTG laboratory (now Géosciences Environnement Toulouse) from 2003 to 2008. Since 2008 he is director of École nationale supérieure de géologie in Nancy.
CONSEILLERS SCIENTIFIQUES (mandat 2020-2023)
Laura Airaghi is a university lecturer at the University of Orléans. She investigates the link between metamorphic reactions (including phyllosilicates) and deformation to better understand the mechanisms that control mineral replacement and the record of the P-T-t-d paths in the mid-upper continental crust. Recently, she explored the link between hydrothermal alteration in granites and strain localization and she started to set up analogue laboratory experiences of deformation in the Griggs apparatus.
Full professor at the Université Claude Bernard, Lyon 1. She is working on the various aspects of fluid-rock interactions in the lithosphere (mechanisms, nature, and kinetic of reactions) and their rheological and geochemical implications. Using a structural, petro-geochemical and mineralogical analysis she is more specialized in oceanic systems (ocean spreading ridges and faults). She combines field work, on land or at sea during oceanographic cruises, with hydrothermal experiments in the lab.
Hervé Cardon is a CNRS Engineer working at the laboratoire de géologie de Lyon. He is a specialist of high-pressure and high-temperature experiments combined with in-situ analysis. His work is focused on the investigation of fluid-mineral interactions from hydrothermal conditions to upper mantle conditions. The goal is to understand the possible consequences for life appearance and microbiological activity at the mineral surface.
Camille Cartier is a young associate professor teaching at the University of Lorraine (France). Her research, conducted at the CRPG (Nancy, France), is focused on magmatic and cosmochemical processes that have led to the formation and evolution of planetary bodies (Earth, Moon, Mercury, asteroids…). Combining experimental petrology, geochemistry and thermodynamical modelling, she works on several topics, linked by a common thread: the impact of the “oxygen fugacity” parameter on phase equilibria and trace element partitioning.
Laura Creon received her PhD from Pierre and Marie Curie University and IFP Energies nouvelles in 2015. She is specialized in analytical coupling for igneous petro-geochemistry problematics. She has done her first post-doc at the Institut Néel (2015-2016) where she studied in-situ X-ray spectroscopy. She continued with a second post-doc at the Universidad Nacional Autonomous de Mexico, UNAM (2016-2017) where she coupled X-ray tomography with igneous geochemistry. Following these two post-doc she took Research and teaching positions at Le Mans (2017-2018) and Sorbonne University (2018-2019) where she worked on the halogens solubility in Earth mantle minerals. She took her actual position as France Manager of X-ray tomography activity at SEMATEC Métrologie in April 2019.
