Bassem Ben Yahia is part of Upstream Process Sciences Group at UCB Pharma in Belgium since 2011 and is focusing on new process technologies for cell culture technologies, media development, process optimization, process intensification and process modeling. Passionate about biology and modelling biological systems, Bassem holds a PhD degree (2017) in Biochemistry & Biochemical Engineering from University of Saarlandes in Germany focused on predictive macroscopic modeling of Chinese hamster ovary cells in fed-batch processes. During his PhD, he successfully developed simple and robust modeling methodologies to predict cell culture performances which is currently used at UCB to accelerate early stage process development.
