In the Mathematical Modelling research group, we use a broad range of mathematical techniques to describe real-world processes. By developing model equations with physical parameters, we help to optimise processes or designs, and predict future behaviour of complex systems.
We have specialists with a diverse range of research interests from the mathematical modelling of biological processes and medicine to investigating radiation damage using atomistic models. The main themes of the group may be broadly described as Mathematical Biology, Materials Modelling, Soft Matter Science, Industrial Modelling, Fluid Mechanics, Quantum Physics and Technology, and Quantum Many-Body Dynamics. The research group has close links to the Interdisciplinary Centre for Mathematical Modelling, with close collaboration with colleagues from other departments.
The biological systems studied range from intracellular processes to those at the scale of organisms and populations. The fluid flows studied range from environmental buoyancy-driven flows to technologically important micro- and nanofluidic flows. The modelling of materials involves the use of mathematical and computational techniques to solve a wide and varied class of problems; this includes nanoscale devices where the fate of individual atoms is important. It spans length scales and time scales that vary over many orders of magnitude and involves the solution of equations that range from continuum to quantum mechanical descriptions. Finally, the dynamical behaviour of large aggregates of quantum particles is studied using numerical and analytical techniques, with a special emphasis on the emergence of universal features (such as the emergence of thermalisation).
