Pierre-François Giroux began his career at the Laboratory of Extreme Materials Technology at CEA Paris-Saclay in 2012. Since 2014, he works on the establishment of R&D studies on additive manufacturing processes, bringing his expertise in metallurgy and mechanics while supervising 7 PhD students. In 2017, he became an Expert at CEA in the field of Applied Metallurgy. He was invited to several international conferences and workshops, and his work was recognized with 19 publications and 5 patents. In 2020, he was awarded the Jacques Gaussens Prize by the French Nuclear Energy Society (SFEN).

In addition to his technical and scientific activities, he coordinated the European project FP7-MatISSE (2016-2017 - 27 partners) and initiated and coordinated the European project H2020-NUCOBAM (2020-2021 - 13 partners), dedicated to the development of qualification processes for powder-based additive manufacturing. Furthermore, in 2022, he contributed to the setup and launch of the ARQANE project (11 partners), a recipient of the "France Relance" French plan for the nuclear sector, which aims to demonstrate and validate the industrial maturity of metal additive manufacturing for the nuclear industry. In 2023, he is leading the "nuclear components" working group within the AM Energy Network, coordinated by Fabrizio Ragusa.
