Research interests:
My research objectives are typically to extract the macroscale consequences of mechanisms operating at much smaller scales, usually the microbiological level, for instance how cells interact and signal, together with the associated biophysics of reaction, diffusion, deformation and flow. This requires detailed mathematical modelling, combined with mathematical analyses, asymptotics, computation and model interpretation within numerous application areas of the life and biomedical sciences. The application areas include cell motility, especially flagellated cell swimming, bacterial dynamics, ecological invasions and mechanisms of biological self-organisation together with the modelling of select processes in physiological transport and solid tumour development.
