Digital tools and capabilities

Projects within Research Stream 2 focus on replicating and optimizing bioprocesses through the development of a comprehensive digital platform that integrates digital twins, virtual models, and Artificial Intelligence.

A key innovation in this stream is the creation of digital twin outputs, which will allow for the exploration of the multi-dimensional design space of bioprocesses, significantly reducing the need for time-consuming and costly wet-lab experiments. These digital twins will be developed through the integration of distinct disciplines, including process mining, machine learning, modelling, and optimisation to provide data-driven predictive solutions of key operations such as cell culture processes and chromatography, and optimise formulation properties.

This project will enable overall process optimisation by examining how relatively sparse high-quality data can be supplemented with lower quality data to enable ‘multi-fidelity’ optimisation for improved decision support for bioprocesses. It will consider approaches that allow searches outside the usual ‘search box’, dynamic optimisation and the development of criteria for the early abandonment of experiments that go wrong.

Automated and explainable machine learning (ML) solutions will be explored in this project to identify and predict product quality attributes, online features, and critical tasks, such as factor analysis, classification, pattern recognition, and outlier and anomaly detection either in data records or work practices. The research will particularly focus on building general online continuous learning and adaptation solutions for predictive models in bioprocesses and unit operations.

Data-driven approaches can be used to enhance decision-making in biopharmaceutical manufacturing. This project specifically examines how multi-criteria decision-making methods can be used at stages such as clone selection, where the most effective high-performance cell lines or clones are selected from a group of genetically identical clones. The project will also consider fault detection, as well as predictive maintenance and advanced forecasting techniques.

Unit operations within the downstream processing stages of bioprocessing are central to this project, which will construct machine learning models to enhance real-time monitoring and process control. ML and AI techniques will be designed to analyse large-scale operational data from the process control platform and optimise the experimental design of key unit operations. Real-time monitoring and control will be improved and predictive methods developed to assist process optimisation.

Digital Twin Approaches for Automated Monitoring, Controlling and Improvement of Bioprocesses

In this project, digital twin technology will be designed, implemented, and evaluated for monitoring, controlling, and improving real-world bioprocesses. An end-to-end digital representation of bio-engineering processes will be built and calibrated using automatically discovered simulation parameters to reflect real-world bioprocesses. The digital twin will provide a mechanism for assessing different scenarios, including configurations that go beyond the limitations of current laboratory equipment. The model will forecast the performance of future bioprocesses, such as expected yield and quality, and aid to identify potential issues at an early stage when interventions are most effective.
