Samuel is Principal Scientist, Materials and Irradiations, within Sartorius FMT Product Development. Samuel has a strong focus on the radiation application work covering a wide range of applications, in link with the sterility assurance topics. Samuel is deeply involved in promoting and facilitating the application of alternative radiation technology to gamma. He is the co-chair of the BPSA X-ray committee, whose objective is to focus on the future of irradiation sterilization in the form of X-ray, as increasing capacity constraints impact delivery for the rapidly growing single-use market. He is one of the lead authors of the 2021 BPSA technical guide, titled “X-Ray Sterilization of Single-Use Bioprocess Equipment. Part I”. He’s also member of the ASTM E61 and of the Irradiation Panel. Samuel is Sartorius’ representative in Team Nablo initiative to conduct and spread-out specific material compatibility upon the different irradiation technologies. He is one of the lead panelists with the Regulatory Bodies (US: Emerging Technology Team (ETT) at the FDA and BARDA; EU: EMA; Japan: PMDA) to discuss technology proposal on X-ray sterilization of SUS since 2021. He is also co-authoring numerous pear reviewed articles on gamma/X-ray/Ebeam impacts on plastic materials.
