This project aims to develop efficient algorithms for simulating the formation of biofilms, which are slimy layers of bacteria and other microorganisms that stick to surfaces. Biofilms can have important implications for health, for example by causing disease or by fouling medical implants; dental plaque is a biofilm that forms on teeth, and Legionnaires’ disease is caused by Legionella bacteria that can grow in biofilms in air-conditioning systems. Biofilm formation is often modelled using individual-based simulations that capture the behavior of each individual bacterial cell, as this allows detailed knowledge of formation mechanisms to be included, but it is very slow for macroscopic biofilms owing to the large number of cells involved and the many interactions between them. In this project we will develop algorithms to aggregate the microscopic features of individual-based biofilm models into system-level models that can predict features of biofilms on a macroscopic scale. A possible approach might be based around so-called equation-free techniques that sample the microscopic model, treating it as a black-box timestepper, in order to estimate the evolution over longer spatial and temporal scales.
