معرفی
Corentin LE GUILLOU is a CNRS Research Fellow at the Materials and Transformations Unit (UMET) of the University of Lille, where he conducts research in the Terrestrial and Planetary Materials team. His work focuses on cosmochemistry, meteoritics, and the early evolution of the solar system through the analysis of extraterrestrial materials such as meteorites and asteroid Ryugu samples.
His research interests span cosmochemistry, meteoritics, planetary science, geochemistry, transmission electron microscopy (TEM), X-ray absorption spectroscopy (STXM), hydrothermal experiments, asteroid Ryugu, chondrites, water-silicate interactions, organic matter in meteorites, experimental petrology, nanomineralogy, and astrobiology. He investigates water-silicate-organic interactions under hydrothermal conditions to simulate early solar system processes. His expertise lies in advanced micro-analytical techniques applied to extraterrestrial samples.
His recent publications (2023–2025) reveal a strong focus on the analysis of Ryugu asteroid samples, with recurring themes in space weathering, organic matter characterization, mineralogical transformations, and aqueous alteration processes. He frequently collaborates with Hugues Leroux and international teams on high-impact studies published in journals like Geochimica et Cosmochimica Acta, Nature Communications, and Meteoritics and Planetary Science. His work bridges experimental simulations with direct sample analysis to understand planetary formation and evolution.
He has co-directed two PhD students: Maxime Morgano (thesis on chondrite water, defended 2023) and Pierre-Marie Zanetta (thesis on electron microscopy of early solar system solids, defended 2019). He is actively involved in major research projects related to asteroid sample analysis and has presented his work at international conferences such as the Lunar and Planetary Science Conference and the Meteoritical Society meetings.
He is part of the Terrestrial and Planetary Materials research group within UMET, which utilizes advanced facilities such as the Lille Electron Microscopy Platform (PMEL) and synchrotron-based techniques for high-resolution analysis of geological and extraterrestrial materials.
