Sugiyama-Badr Laboratory

Our goal is to develop algorithms to find design conditions (i.e., design space) that meet the quality requirements for cell pharmaceuticals in mesenchymal stem cell production processes, which is a complex and uncertain process. The following topics are mainly tackled:
　• Hybrid modeling by combining dynamic models and image information.
　• Stochastic simulation by categorization and parameterization of variation origins and Monte Carlo approach.
　• Design space determinations that incorporate dynamic and stochastic variations in cell quality.
