Research in the Fuller group studies the flow behavior of complex soft materials. This focus naturally combines the subjects of fluid mechanics and materials science, which are brought together in the science of rheology. Broadly defined, rheology is the science of flow and deformation of complex materials and has wide applications in numerous areas that impact human health, the energy sciences, and the environment. In the sections below, various projects are described that illustrate how approaches in the Fuller laboratory address each of these areas.
