Research Interests:

I am a cosmochemist interested in understanding the conditions of formation and chronology of the first objects in the early solar system (e.g., chondrules). I am studying meteorites, formed at the beginning of our solar system at around 4.56 billion years ago, by combining petrological observations and isotopic analyses. I am mainly performing mass spectrometry, such as secondary ion mass spectrometry (SIMS) and inductively coupled plasma mass spectrometry either with solutions (MC-ICP-MS) or laser ablation (LA-MC-ICP-MS/MS).

Education and Employment:

Since 2023: Postdoc, Max Planck Institute for Solar System Research, Göttingen, Germany.
2019-2023: PhD thesis in cosmochemistry (geosciences), Centre de Recherches Pétrographiques et Géochimiques (CRPG), Centre national de la recherche scientifique (CNRS), Université de Lorraine, Nancy, France.
2017-2019: Master of Sciences in Earth sciences, Université de Lorraine, Nancy, France.
2015-2019: Engineering degree, École Nationale Supérieure des Mines de Nancy, Nancy, France.
