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.
