Research Overview

Creation of extremely strong yet ultra-light materials can be achieved by capitalizing on the hi­e­r­a­­r­chical design of 3-dimensional nano-lattices. Such structural meta-materials exhibit superior thermo­mechanical pro­­­per­­ties at ex­tre­me­ly low mass densities (lighter than aerogels), making these solid foams ideal for many scientific and tech­no­lo­gi­cal applications, especially in the medical field. The medical research thrusts in the Greer group span from biomimicking to creating nanostructured 3-dimensional scaffolds for cell growth to body-compatible batteries to power devices like pacemakers. A new pursuit in her group is to investigate the mechanical properties of trabecular bone, focusing on the effects of anisotropy on fracture and deformation behavior with the goal of creating more resilient artificial bones.
