Development of next generation bioreactor models

Industrial biotechnology is increasingly being seen as a way in which we can sustainably produce the products we need. These include plastics, pharmaceuticals, chemicals, food ingredients and many others. A key challenge in this area is developing modelling tools which can be used to describe the complex processes occurring inside large-scale industrial bioreactors.

The aim of this project would be to build on previous work to develop the next generation of bioreactor models. Existing models have generally been developed for well characterised microorganisms (e.g. Saccharomyces cerevisiae or Escherichia coli) producing simple products. There is a need to extend these models to both the production of different microorganisms, as well as the production of a broader range of products.

This project will be primarily computational, but may involve some lab-based work. Students working on this project will:

  1. Develop models that relate the design and operating parameters of a bioreactor to the process performance.
  2. Validate these models against either industrial datasets or experimental data.


Applicants should have a First Class or Upper Second Class Honours degree, or an MSc in chemical engineering, biotechnology or a related discipline. Applicants would ideally have some experience with mathematical modelling and computer programming. Applicants should be able to work independently, have good written and oral communication skills and be self-motivated.
