Présentation

Après des études d'ingénierie spécialisée dans l'aéronautique et l'aérospatiale, j'ai obtenu mon doctorat en physique en étudiant la rétention d'hydrogène dans les composites à base de fibres de carbone utilisés comme matériaux de première paroi dans les réacteurs de fusion. Alors que la communauté s'orientait vers les matériaux métalliques, j'ai rejoint l'Institut national des sciences de la fusion au Japon pour un poste de post-doctorante, afin de travailler sur le stellarator LHD et de caractériser l'impact de l'irradiation à l'hélium sur la microstructure du tungstène. J'ai ensuite participé au projet PassivITER visant à évaluer l'inventaire du tritium dans les poussières de tungstène en collaboration avec des biologistes qui étudient l'impact potentiel de la toxicité sur les tissus pulmonaires. Depuis 2016, je coordonne l'analyse des matériaux du tokamak WEST après exposition aux différentes campagnes expérimentales, dans le cadre d'un effort international soutenu par le consortium EUROfusion. Je suis l'experte référente des activités sur le tritium menées par l'IRFM, et la coordinatrice du projet transversal fusion/fission TITANS (Tritium Impact and Transfer in Advanced Nuclear reactorS) financé par Horizon Europe.
