Many complex systems are only accurately described by fine-scale models, but for scientific and engineering applications require simulations over a macroscale domain. Large-scale simulations of these systems using fine-scale models are prohibitive in computational time and infeasible in terms of data storage requirements. To overcome these issues, I develop systematic mathematical and computational methods for compact and accurate macroscale modelling of complex systems.
