Abstract:

Digital twin (DT) has become a rapidly expanding approach in various manufacturing fields including biologics industry. Basically, bioprocess DT combines physical system and its complementing digital counterpart via real-time monitoring and data collection, thus enabling their interactive communications for enhancing operational efficiency and reliable product supply of biomanufacturing processes. DT can be realized through developments and applications of emerging technologies in advanced soft-sensor, data management, advanced data analytics with artificial intelligence (AI) and mechanistic models representing the cells and bioreactor for virtually mirroring their behaviors under adjustable process conditions. In this talk, I will present our recent achievements and on-going efforts for in line monitoring as well as key components of virtual part within the bioprocess DT platform [1-7]. They include machine/deep learning algorithms for forecasting multi-step ahead profiles of cell culture performance, and genome-based mechanistic model of industrially relevant Chinese hamster ovary (CHO) cells for real-time simulations. Both components can be hybridized to describe their dynamic cellular behaviors and metabolic states given culture conditions, thus allowing us to effectively identify process bottlenecks and key engineering targets, suggest various control strategies to improve reliability, efficiency and efficacy of intricate bioprocess operations.
