Presentation

Docteur en Astro-minéralogie, ma thèse m'a permis de développer de nombreuses compétences en microscopie électronique à balayage et en transmission. L'étude de matériaux complexes que sont les météorites primitives m'a aussi amené à développer de nombreux outils de traitement de données sur Python et Matlab pour quantifier des objets hétérogènes à l'échelle micro/nanométrique. Ces outils sont basés sur des données de spectroscopies et vont de la déconvolution de spectres à la modélisation des interactions électrons-matière. Ces outils sont accessibles sur Github et sont pour certains implémentés sur le logiciel Hyperpsy. Durant mon doctorat j'ai aussi pu développer de nombreuses animations scientifiques portant sur l'astronomie et m'amenant à rencontrer de nombreuses personnes que cela soit dans le même domaine où de tout horizons. Durant mes post doctorat je suis parti à l'étranger en Arizona ou j'ai continuer mes travaux sur les matériaux primitif du système solaire. Je travail en ce moment pour le CNRS, sur la minéralogie des inclusions présentes dans des verres d'impacts.
