In 2014, Marie obtained her Master’s degree in Cellular Engineering at Université de Lorraine (Nancy) after a seven-months internship at Promethera Biosciences (Mont-Saint-Guibert, Belgium) where she investigated senescence of liver progenitor cells.

She worked as an engineer in the field of oncology at Institut de Biologie de Lille (UMR8161, 2015-2016) and developped microfluidic cell culture in the BioMEMS team of Institut d’Électronique, de Microélectronique et de Nanotechnologie (IEMN, UMR8520, Université de Lille, 2016-2017).
