eMICP (Engineering Microbial-Induced Carbonate Precipitation via Meso-Scale Simulations) is an EPSRC funded project which brings together researchers from Newcastle, Bath, and Cardiff Universities. The project's aim is to promote the rational design of self-healing systems through understanding the link between bacterial metabolism, concrete chemistry, and biomineralisation. We propose a radical new approach to the challenge of engineering the mesoscale: one that combines advanced modelling, simulations, and experiments.
