Samuel Marre is a senior researcher at CNRS at the Institute of Condensed Matter Chemistry in Bordeaux and head of the Supercritical Fluids group. After obtaining his PhD at the University of Bordeaux, he worked as a postdoctoral researcher with Klavs F. Jensen and Moungi G. Bawendi at the Massachusetts Institute of Technology on the development of new methods for synthesizing quantum dots in microfluidics. He has since become a recognized expert in the development of multi-scale high pressure and high temperature experiments. He uses these tools to study various applications, including thermo-hydrodynamics, materials synthesis, geological storage and bio-geoconversion of CO2, and the study of deep environments. Samuel Marre received the CNRS bronze medal in 2014 and obtained two ERC grants to study the (bio)chemical valorization of CO2 into methane and hydrogen, in particular via mineral carbonation processes.
