DESCRIPTION:Prof. Chiara Dariao\nBio: Professor Daraio’s interests resid
 e at the interface of materials science\, condensed matter physics and sol
 id mechanics\, particularly in the design\, development and testing of mul
 ti-scale metamaterials and phononic crystals. She received her 5 year Laur
 ea degree in Mechanical Engineering from the Universita’ di Ancona\, (Un
 iversita’ Politecnica delle Marche)\, Ancona\, Italy (2001). She receive
 d her M.S. (2003) and Ph.D. degrees (2006) in Materials Science and Engine
 ering from the University of California\, San Diego. Chiara joined the Aer
 onautics and Applied Physics departments of the California Institute of Te
 chnology (Caltech) in fall of 2006 and was promoted full professor in 2010
 . As of January 1st\, 2013\, she joined the department of Mechanical and P
 rocess Engineering at ETH Zürich\, with a chair in Mechanics and Material
 s. She has been a guest researcher at the Lawrence Berkeley National Labor
 atories (NCEM)\, a visiting research physicist at the Scripps Institute of
  Oceanography (San Diego) and won several awards. Among these\, she receiv
 ed 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 Youn
 g Investigator Award in 2010. She she is also a winner of the NSF CAREER a
 ward (2009) and of the Richard Von Mises Prize (2008). She published over 
 70 peer-reviewed papers\, two book chapters and six patents. For a complet

 l role in the design of new materials\, providing the fundamental rules an
 d guidelines for predicting the response of engineered systems. The starti
 ng point of our research are well understood nonlinear local phenomena\, s
 uch as elastic Hertzian contact interactions between particles\, or the de
 formation of micro- and nano-structures. Exploiting these local phenomena\
 , we develop new materials and devices with novel global mechanical proper
 ties. I will discuss recent progress in the experimental study of nonlinea
 r 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 vi
 brations and explosive blasts\, or have very low thermal expansion coeffic
 ients.
