Romain Garrigue - Founder

Romain Garrigue - Founder

Romain Garrigue, CNAM Engineer, 18 years of experience in nuclear engineering. My career began at IRSN (ASNR), where I worked as a Project Engineer on the CABRI program. Then I led projects for key industry players—TechnicAtome, CEA, Framatome, ITER, and Naval Group—while at TechnoPlus Industries. As a Manufacturing Engineer at ATG Europe  (F4E), I also contributed to the ITER project. My expertise covers design, manufacturability, and technical management of complex projects. Based on this extensive experience, I founded NUMA to apply my skills to innovative and demanding nuclear projects.
