Prof. Chiara Dariao Bio: Professor Daraio’s interests reside at the interface of materials science, condensed matter physics and solid mechanics, particularly in the design, development and testing of multi-scale metamaterials and phononic crystals. She received her 5 year Laurea degree in Mechanical Engineering from the Universita’ di Ancona, (Universita’ Politecnica delle Marche), Ancona, Italy (2001). She received her M.S. (2003) and Ph.D. degrees (2006) in Materials Science and Engineering from the University of California, San Diego. Chiara joined the Aeronautics and Applied Physics departments of the California Institute of Technology (Caltech) in fall of 2006 and was promoted full professor in 2010. As of January 1st, 2013, she joined the department of Mechanical and Process Engineering at ETH Zürich, with a chair in Mechanics and Materials. She has been a guest researcher at the Lawrence Berkeley National Laboratories (NCEM), a visiting research physicist at the Scripps Institute of Oceanography (San Diego) and won several awards. Among these, she received a Presidential Early Career Award (PECASE) from the White House in 2012, was elected as a Sloan Research Fellow in 2011 and received an ONR Young Investigator Award in 2010. She she is also a winner of the NSF CAREER award (2009) and of the Richard Von Mises Prize (2008). She published over 70 peer-reviewed papers, two book chapters and six patents.

Mechanics plays a central role in the design of new materials, providing the fundamental rules and guidelines for predicting the response of engineered systems. The starting point of our research are well understood nonlinear local phenomena, such as elastic Hertzian contact interactions between particles, or the deformation of micro- and nano-structures. Exploiting these local phenomena, we develop new materials and devices with novel global mechanical properties. I will discuss recent progress in the experimental study of nonlinear acoustic crystals and periodic metamaterials. These materials consist of building blocks with fixed geometries (e.g., spheres or plates) that are arranged in precise (1 to 3D) lattices. By designing the lattice geometry, we construct systems that can redirect mechanical waves, can absorb vibrations and explosive blasts, or have very low thermal expansion coefficients.
