We live in a world of designed materials, however, the design principles often lack a fundamental understanding of how the chemical nature of the constituents leads to the bulk properties of choice. Work in the Lipson Group is focused on creating a bright line between the microscopic nature of complex materials and their macroscopic behaviour. We use simulations, as well as the tools of statistical mechanics and thermodynamics. Areas of particular interest involve glassiness and dynamic heterogeneity in the bulk and in thin films, the effect of interfaces on polymer film properties, and phase behavior in polymer solutions and blends. Our specialty involves developing simple, minimalist descriptions that capture the fundamental physical behaviour, and that are held accountable to experimental results.
