About the Project

It is increasingly appreciated that the material on which a cell is cultured can have a profound influence on its growth and differentiation. It is therefore essential that we can prepare bespoke materials with user-specified properties to enable us to take a Precision Medicine approach to cell culture for regenerative medicine applications. An example is the production of human liver cells, for the repair of damaged or diseased livers, by the differentiation of iPCSC (induced pluripotent stem cells) into liver cells. Being able to design, and make, a matrix for cell growth, which is optimally tuned to the requirements of liver cells, would enable a precision medicine approach, rather than ‘one size fits all’.

The collaboration between Regan and Goddard seeks to move beyond the current experimental ‘trial and error’ approach to preparation of such matrices (hydrogels). In this project, the student will develop a modelling hierarchy for hydrogel formation, including numerical implementations and mathematical analysis of appropriate limits. The close collaboration between the Regan and Goddard labs will allow us to test model predictions experimentally. Ultimately, we will develop a predictive model for these hydrogels, which will enable us to design new materials, whose properties are specified a priori. We will thus be able to precisely fine-tune the design of the matrices so they are optimal for the growth and differentiation of different cell types. Thus, work will have an enormous impact in the area of precision regenerative medicine. We collaborate with the laboratory of David Hay (CRM), a liver regeneration expert. Through this collaboration we will be able to test the hydrogels in realistic applications as matrices for cell growth and differentiation.

The student will be a member of an interdisciplinary research community. Being part of the Precision Medicine cohort, they will gain a deep understanding of the potential scope and application of modeling in experimental biomedical research. The Regan group is experimental and interdisciplinary. In working on a collaborative project with the Regan and Goddard groups, the student will gain a deep understanding of the importance of a strong and reciprocal interplay between modeling and experiment. The student will be a member of the Applied and Computational mathematics theme, with associated opportunities to attend relevant seminars and research events, including presenting their research. They will learn a range of modelling techniques, both discrete and continuous, alongside the associated computational methods and underlying theory. They will interact with students in the MAC-MIGS CDT, an EPSRC-funded PhD programme in mathematical modelling, analysis and computation. Additional opportunities to enhance their professional skills will be via participation in public engagement activities with the Goddard and Regan laboratories.

This project is well-suited to students with undergraduate or masters degrees in applied mathematics, or a related subject, which includes mathematical modelling, who have an interest in applying their expertise in the Precision Medicine setting. Students with backgrounds in the biological and physical sciences, who have a strong interest in quantitative approaches are also encouraged to apply.

This MRC programme is joint between the Universities of Edinburgh and Glasgow. You will be registered at the host institution of the primary supervisor detailed in your project selection.

All applications should be made via the University of Edinburgh, irrespective of project location. For those applying to a University of Glasgow project, your application along with any supporting documents will be shared with University of Glasgow.
