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