EPSRC Innovative Manufacturing Research Centre (IMRC) in Bioprocessing
The multi-disciplinary Innovative Manufacturing Research Centre (IMRC) in Bioprocessing draws upon academic expertise from a wide range of UCL departments as well as from recognised experts in other institutions throughout the UK. The IMRC has a single focus:
- To change fundamentally the ways in which bioprocesses are developed for the manufacture of complex and highly specific next-generation biopharmaceuticals.
The research activities of the IMRC are designed to meet this goal as set out below. Collaborative doctoral and post-doctoral projects are currently underway in each of these and funded by a combination of BBSRC, EPSRC and Technology Strategy Board awards.
- Novel approaches to the creation of microscale mimics of key unit operations.
- Engineering studies to construct sequences of bioprocess operations on automated platforms for rapid bioprocess creation and optimisation.
- Development of intelligent experimental design algorithms to make best use of microscale approaches.
- Creation of techniques to maximise knowledge acquisition from sparse datasets.
- The use of host cell engineering to remove process bottlenecks.
- Identification and deployment of smart downstream process solutions designed to achieve significant improvements to process yield and efficiency.
IMRC studies consider the whole bioprocess division. The improvements in overall process peformance that may be realised by all engineering for example, can be mimiced using multi litre quantities of materials and then verified in the unique pilot-plant facilities at UCL.
The IMRC programme products employs a series of industrially relevant expression systems and macromolecular products to explore the challenges and to illustrate its research successes. These include expression of antibody fragments in E.coli, whole antibodies in mammalian cell lines and virus-like particles from S. cerevisiae.
A multi-disciplinary group of UCL academics with an extensive history of close collaboration work to deliver the IMRC vision. These include Professor Mike Hoare (micro-scale bioprocessing), Professor Nigel Titchener-Hooker (whole bioprocessing), Professor John Ward (Department of Biochemistry and Molecular Biology: cell engineering), Dr. Tony Hunter (Computer Science, knowledge acquisition), Dr. Dan Bracewell (smart downstream processing), Dr. Yuhong Zhou (intelligent design methods), Dr. Eli Keshavarz-Moore (fermentation) and Dr. Frank Baganz (metabolic modelling and engineering).
A consortium of 12 companies supports the programme financially and through the promotion of industrial strains and materials. Additionally they form an industrial Steering Group to assist in the direction of the programme. A senior Management Committee provides strategic direction to the IMRC and in particular helps with outreach via the KTNs and other IMRCs. Current consortium members include: BioPharm Services (UK), Eli Lilly (UK & USA), GE Healthcare (UK & EU), GSK (UK), Health Protection Agency (UK), Lonza Biologics (UK, EU & USA), Medimmune (UK), Merck (USA), Novo Nordisk (EU), Protherics (UK), Pfizer (UK & USA) and UCB (UK).
The capacity to determine critical engineering parameters early in evolution of a bioprocess design lies at the heart of the IMRC philosophy. Increasingly we are employing the use of highly automated and miniaturised systems to investigate key aspects of bioprocess behaviour.
The IMRC sponsors regular IMRC Bioprocess Briefing at UCL which are open to all. Outreach to the community is further stimulated by Special Interest Groups (SIGs), for example on the use of microwell technologies in bioprocess discovery and optimisation. The IMRC hosts an annual meeting each September to showcase its success and the extensive collaborations both academic and industrial that it supports.
Understanding the impact of press changes is critical if advances are to be made across the unit operations within a bioprocess. Pioneering confocal microscopy studies of the impact that foulants have on the uptake of product molecules during adsorption are typical of the fundamental studies underway within the IMRC.
