Research interests:

Cosmochemistry, Astrobiology, Meteorites, Planetary Science, Isotope Geochemistry, Geology.

Career history:

BSc in Geology in 2015 from the Université du Québec à Chicoutimi (UQAC), Chicoutimi (QC), Canada.
MSc cum laude in Earth and Planetary Sciences (Geochemistry) from the Université Paris Diderot, in partnership with the Institut de Physique du Globe de Paris, and the École Normale Supérieure de Lyon, France.

Active research projects:

I am a Ph.D. candidate in Planetary Science at the University of Glasgow (UK) investigating Calcium-Aluminium-rich Inclusions (CAIs) within CM (Mighei-like) carbonaceous chondrites using Scanning Electron Microscopy (SEM), Energy-Dispersive X-ray Spectroscopy (EDS), Electron Backscatter Diffraction (EBSD), Electron Probe Microanalysis (EPMA), Secondary Ion Mass Spectrometry (SIMS), Transmission Electron Microscopy (TEM), Transmission Kikuchi Diffraction (TKD), and Raman Spectroscopy.
My main areas of focus are (1) geochemical and petrographic analyses of meteorites (specifically carbonaceous chondrites) to determine the origin of Earth’s water; (2) geophysical surveys of terrestrial impact craters to better characterize their morphology and evolution to understand their planetary counterparts; (3) thermodynamic modelling of planetesimal and asteroid core formation and differentiation processes.
