  Talk Title: Materials by Design: 3-Dimensional Nano-Architected Meta-Materials
  
  Abstract: Creation of extremely strong and simultaneously ultra lightweight materials can be
  achieved by incorporating architecture into material design. We fabricate threedimensional
  (3D) nano-architectures, i.e. nanolattices, whose constituents vary in size
  from several nanometers to tens of microns to centimeters. These nanolattices can
  exhibit superior thermal, photonic, electrochemical, and mechanical properties at extremely
  low mass densities (lighter than aerogels), which renders them ideal for many
  scientific pursuits and technological applications. The dominant properties of such
  meta-materials, where individual constituent size at each relevant scale (atoms to
  nanometers to microns) is comparable to the characteristic microstructural length
  scale of the constituent solid, are largely unknown because of their multi-scale nature.
  To harness the beneficial properties of 3D nano-architected meta-materials, it is
  critical to assess properties at each relevant scale while capturing the overall structural
  complexity.
  We describe the deformation, as well as the mechanical, biochemical,
  electrochemical, thermal, and photonic properties of nanolattices made of different
  materials with varying microstructural detail. Attention is focused on uncovering the
  synergy between the internal atomic-level microstructure and the nano-sized external
  dimensionality, where competing material- and structure-induced size effects drive
  overall response and govern these properties. Specific discussion topics include the
  nanofabrication and characterization of (often hierarchical) three-dimensional nanoarchitected
  meta-materials and their applications in chemical and biological devices,
  ultra lightweight energy storage systems, damage-tolerant fabrics, and photonic
  crystals.
  
  Biography: Greer's research focuses on creating and characterizing classes of materials with multiscale
  microstructural hierarchy, that utilize the combination of three-dimensional (3D)
  architectures with nanoscale-induced material properties. These include nature-made
  materials, i.e. bone and hard biological systems, as well as synthetic ones that can be
  comprised of a broad range of materials: from ceramics and metals to glasses, polymers,
  organics, organic/inorganic hybrids, and multi-functional smart materials. These nanoarchitected
  meta-materials not only provide a rich "playground" for fundamental
  science but also have the potential to enable new technological advances in biomedical
  devices, battery electrodes, lightweight structural materials, and
  Greer obtained her S.B. in Chemical Engineering with a minor in Advanced Music
  Performance from MIT in 1997 and a Ph.D. in Materials Science from Stanford, worked
  at Intel (2000-03) and was a post-doc at PARC (2005-07). Julia joined Caltech in 2007
  and currently is a full professor with appointments in Materials Science, Mechanical
  Engineering, and Medical Engineering.
  Greer has more than 130 publications and has delivered over 100 invited lectures, which
  include 2 TEDx talks, multiple named seminars at universities, the Watson lecture at
  Caltech, the Gilbreth Lecture at the National Academy of Engineering, the Midwest
  Mechanics Lecture series, and a "IdeasLab" at the World Economic Forum. She was
  named a Vannevar-Bush Faculty Fellow by the US Department of Defence (2016) and
  CNN's 20/20 Visionary (2016). Her work was recognized among Top-10 Breakthrough
  Technologies by MIT's Technology Review (2015). Greer was named as one of "100
  Most Creative People" by Fast Company and a Young Global Leader by World
  Economic Forum (2014) and received multiple career awards: Kavli (2014), Nano
  Letters, SES, and TMS (2013); NASA, ASME (2012), Popular Mechanics
  Breakthrough Award (2012), DOE (2011), DARPA (2009), and Technology Review's
  TR-35, (2008).
  Greer serves as an Associated Editor for Nano Letters and Extreme Mechanics Letters.
  She is also a concert pianist, with recent performances of "nanomechanics rap" with
  MUSE/IQUE, solo piano recitals and chamber concerts (2007-present), and as a soloist
  of Brahms Concerto No. 2 with Redwood Symphony (2006).
