With core expertise in the mechanics and physics of materials, the research team of Daniel Wagner is conducting experimental and modeling work to understand and optimize the mechanical behavior at the micro- and nano-scale of synthetic and biological composites. The team is trying to address fundamental questions: How do specific composites (composites with a given microstructure) function? How to mimic Nature’s intricate (hierarchical, multi-scale) materials and their properties? What are the roles of scale, symmetry, and geometry? How to develop techniques for “nanomeasurements”? Which experimental approach to adopt for the development of new composite materials?
