Graduate of the École Nationale Supérieure de Géologie (ENSG, Nancy), Guillaume Avice got his PhD in Geosciences in 2016 at the CRPG (Université de Lorraine, Nancy). He then took a Postdoctoral scholar position at the California Institute of Technology (Caltech, USA) for two years where he collaborated with teams of the Jet Propulsion Laboratory (Caltech/NASA, USA) to develop a miniaturized mass spectrometer for space missions. He joined the IPGP in 2018 as a postdoctoral researcher and was appointed "Chargé de Recherche CNRS" at the IPGP in 2020. His work concerns the origin and evolution of planetary atmospheres. He is measuring the elemental and isotopic compositions of noble gases and nitrogen in ancient rocks to understand the history of atmospheres and planets.
Elodie Lebas got her PhD in geophysics at the IPGP in 2012. From 2013 to 2020, she conducted her postdoctoral research in Kiel, Germany, first at the GEOMAR Institute (2013-2015) and then at the Christian-Albrecht University (2015-2020). She then did a postdoctorate at the University of Lisbon in Portugal, before being recruited as an Assistant Physicist in the Marine Geosciences team of the IPGP to work on the current seismo-volcanic crisis off Mayotte within the REVOSIMA (Volcanological and Seismological Monitoring Network of Mayotte). Her research is based on the analysis of marine geophysical data in order to reconstruct the paleo-environmental history of sedimentary basins off volcanic islands and in lacustrine settings, and to identify the geological and instabilities processes affecting them over time. She also reconstructs the past eruptive activity of oceanic volcanic islands through marine tephrochronology studies.
Cécile Prigent obtained her PhD in Earth Sciences at ISTerre (Université Grenoble-Alpes) in 2017. She then conducted three years of postdoctoral research at the University of Delaware (USA), before being recruited as an assistant professor at the IPGP in 2020 in the Marine Geosciences team. Her research focuses on the rheology of the lithosphere at plate interfaces, with a particular interest in constraining the feedback mechanisms between fluids and rock deformation and their consequences on seismic processes. She works mainly from the study of natural samples using an interdisciplinary petrological, (micro)structural and geochemical approach to trace the circulation of fluids and characterize the impacts of fluid-rock interactions on the mechanical behaviour of rocks.
Lise Retailleau obtained her PhD in Earth and Environmental Sciences at the IPGP in 2015. She then goes to ISTerre (Grenoble) for a post-doctorate. In 2017, she joins Stanford University (School of Earth) in California as a Post-doctoral Scholar. She finally joined the IPGP in February 2020 as a post-doctoral fellow at the OVPF before being appointed Assistant Physicist at the IPGP in September 2020. Her work focuses on the analysis of signals recorded by seismological networks for the study of sources ranging from volcano-tectonic seismicity in Mayotte to tropical cyclones.
