A persistent feature of complex systems in engineering and science is the emergence of macroscopic, coarse grained, coherent behaviour from the interactions of microscopic agents (molecules, cells, grains) and with their environment. In current modeling, ranging from ecology to materials science, the underlying microscopic mechanisms are often known, but the closures to translate microscale knowledge to a system level macroscopic description are rarely available in closed form. Our novel methodology will explore this stumbling block, and promises to radically change the modeling, exploration and understanding of multiscale complex system behaviour.Read moreRead less

In modern science and engineering many complex systems are described by distinctly different microscale physical models within different regions of space. This project is to develop systematic mathematical and computational methods for the compact and accurate macroscale modelling and computation of such systems for application in industrial research and development. Our sparse simulations, justified with mathematical analysis, use small bursts of particle/agent simulations, PDEs, or difference equations, to efficiently evaluate macroscale system-level behaviour. The objective is to accurately interface between disparate microscale models and establish provable predictions on how the microscale parameter spaces resolve at the macroscale.Read moreRead less

In order to test fundamental quantum field theories, which underlie all physical phenomena from galaxy formation to the behaviour of biological system, it is necessary to be able to solve these theories in all regions of interest. In particular, solving theories in the nonperturbative regime has proven a difficult and challenging problem. The most successful theory that we have in physics is perturbative quantum electrodynamics, even though in the nonperturbative regime it is widely believed to be a trivial or pathological theory. We will build on exciting recent successes in this field and use advanced supercomputers to understand the detailed nonperturbative behaviour of quantum electrodynamics.Read moreRead less
