Samuel Marre – CNRS Researcher

Head of the BIG MAC project, Samuel Marre was born in France in 1979. He received his MSc and PhD in Chemical Engineering from the ENSCBP (Bordeaux, France) in 2003, and from the University of Bordeaux in 2006, respectively. He then joined the Jensen Lab at MIT as a postdoctoral associate from 2006 to 2008, working on high pressure microsystems and then spent one year at the Laboratory of the Future (Solvay – CNRS) in 2009. He is currently a CNRS researcher at the Institute of Condensed Matter Chemistry of Bordeaux (ICMCB). Samuel Marre’s research focuses on the study and use of high pressure / high temperature fluids in confined environments (“Supercritical Microfluidics”). In particular, it includes the development of high pressure and high temperature microreactors to study various complex phenomena including thermodynamics, hydrodynamics, chemistry and geobiology. These are dedicated to various applications such as the synthesis of nanomaterials, the study of precipitation processes or the mechanisms related to CO2 geological storage and CO2 bioconversion in geological environment. This leads simultaneously to develop an original micro-instrumentation incorporating various techniques for the in situ characterization of fluids under extreme conditions. Samuel Marre was awarded the bronze medal of CNRS in 2014 from the section “Reactive fluidic media”.


Anaïs Cario – Associate Researcher

Anaïs Cario is a High-Pressure geo-microbiologist. She is interested in the eco-physiology of deep-biosphere microorganisms.  In the lab, she mimics the deep-biosphere environments in order to elucidate the biological strategies of microorganisms living in high-pressure environments.
She obtained her PhD in 2013 at the University of Lyon, France, under the supervision of Dr. Phil Oger (Lab of Earth and Environmental Sciences). She worked then as a postdoctoral researcher in Dr. Karyn L. Rogers’ lab at RPI (Habitability and Extreme Life Laboratory, Rensselaer Polytechnic Institute, Troy NY, USA).
She joined the BIG MAC project in November 2017 as a Associate Researcher. Her work focuses mostly on the biological part of the project. Her goal is to better understand the mechanisms associated with the bioconversion of CO2 (i.e. methanogenesis process) in deep aquifers. In this purpose, she is growing and stuying methanogens using the microfluidic tools (Geological Labs on Chips – GloCs) to reproduce the in situ geological environments (i.e. pore scale, high pressure & high temperature conditions).


Cyrielle Fauveau  – PhD student

Cyrielle Fauveau studied material engineering at the Higher Institute of advanced Materials and Mechanics of Le Mans (France), where she obtained her Engineer degree in 2017. She started her Ph.D thesis in november 2017 at the Institute of Condensed Matter Chemistry of Bordeaux (ICMCB), under the supervision of Dr. Samuel Marre and Dr. Cyril Aymonier. In the ERC BIG MAC project, she is interested in the in situ hydrogen production through iron corrosion in multiphasic CO2/water media under pressure and temperature conditions encountered in deep aquifers.  For this purpose, she uses high-pressure microreactors to recreate these geological conditions at a pore scale. She studies solids transport in multiphasic flows in porous media, iron corrosion under specific conditions and she develops optimal parameters for the production of hydrogen. Hydrogen is critical for the bioconversion of CO2 to CH4 by methanogens.


Maxence Perroux – PhD student

Graduated in 2016 from the Graduate School of Chemistry, Biology and Physics ENSCBP of Bordeaux (France), Maxence Perroux started his PhD thesis in February 2018 at the Institute of Condensed Matter Chemistry of Bordeaux (ICMCB). Under the supervision of Dr. Samuel Marre and Dr. Sebastien Dupraz (BRGM, Orléans), he is investigating the methanogens growth and their methane production rates under geological conditions within the context the ERC BigMac project. To achieve this goal, methanogens natural environnements (deep saline aquifers) are reproduced by high-pressure porous microreactors. Consuming carbon sources to grow amongst other things, the objective is to adapt these methanogens to a medium with CO2 as only carbon source. 

Emeline Vidal  – PhD student

Emeline Vidal obtained her degree of Fundamental and Applied Microbiology at the University of Western Brittany of Brest in 2019. She started her PhD thesis in October 2019 at the Institute of Condensed Matter of Bordeaux (ICMCB). For the BIG MAC project, under the supervision of Dr. Samuel Marre and Dr. Anthony Ranchou-Peyruse (UPPA, Pau), she is working on the methanogens growth and their methane production by mimicking their natural environment (geological conditions). The objectives of her work is to determine the localization of the produced methane in porous media model and to identify key parameters to optimize the CO2 bioconversion.

Carole Lecoutre – CNRS Research Engineer

Carole Lecoutre is a CNRS research engineer in the Supercritical Fluids group at ICMCB, in charge of scientific instrumentation development and experimental techniques. She is currently involved in two main activities associated to experiments using near critical fluids. The first activity is associated to space experiments with the DECLIC instruments on board the International Space Station, to study boiling phenomena, heat and mass transfer in dense, thermo-compressible, near-critical fluids under microgravity.  The second activity concerns the development of microfluidic techniques at high-pressure and high temperature, for the study of near-critical fluids and geofluids.
For the BIG MAC project she is in charge of managing the website. With Olivier she also manages some equipments, such as the high resolution confocal imaging microscope (Leica TCS SP8 8kHz) and the Fourier transformed infrared microscope (Agilent Cary 630 / FTIR Cary 670 spectrometer).


Olivier Nguyen – CNRS Assistant Engineer

Olivier Nguyen is a CNRS Assistant Engineer in the Supercritical Fluids group at the Institute for Condensed Matter Chemistry of Bordeaux since 1998. Olivier joined the group in January 2016 for supporting the clean room activity. Within the BIG MAC project, he’s the manager of the McLab (BIG MAC’s laboratory), specifically in charge of the design and layout of the project’s experiments and the maintenance of the equipment. Meanwhile, his activities also concern the microfabrication / development (in the clean room) and the implementation of the new transparent Biogeological Labs on Chip (BioGLoCs) and their coupling with the experimental lab environment.


Matthieu Renaudin – CNRS Administrative support

Matthieu Renaudin is currently in charge of the financial service of ICMCB Laboratory since April 2016. He has joined the BIG MAC ERC Project in November 2017 to manage the administrative and financial parts. He advises the team on financial aspects of the project and is in contact with all of financial partners regarding depenses to do.
