DESCRIPTION:Prof. Ting Xu\, Department of Materials Science and Engineerin
 g - Department of Chemistry - University of California Berkeley\nThe key t
 o future technology is the design and fabrication of functional materials 
 having structures ordered down to the molecular level. With the rapid deve
 lopments in material chemistry and polymer science\, many molecular buildi
 ng blocks can be readily synthesized. However\, to generate functional mat
 erials that can be used to address challenges facing our society\, we must
  develop approaches to organize them into macroscopic materials in a contr
 olled manner\, while maintaining structural control from the atomic level 
 to macroscopic distances. These require us to select the right building bl
 ocks\, understand the principles underpinning the self-assembly\, and use 
 these principles to direct the assemblies at various length scales to obta
 in targeted functional materials. More importantly\, we need to develop a 
 versatile methodology to generate new functional materials simply by subst
 ituting building blocks\, instead of re-building them from scratch.  Howe
 ver\, the challenges to achieve hierarchical structural control in a multi
 -component system rest in the high entropy and the complex interactions in
 volved. Inspired by nature\, my research aims to use secondary interaction
 s and the entropy of the polymer chain in conjunction with spatial confine
 ment to achieve hierarchical assemblies in multiple component polymeric ma
 terials. I am going to discuss some of on-going research efforts focus on 
 building blocks including polymers\, nanoparticles\, small molecules\, sup
 ramolecules\, peptides and proteins to generate functional materials with 
 interesting biological\, optical and magnetic properties.\nReference:\n1.

  Ting Xu received her Ph.D from the Department of Polymer Science and Engi
 neering from the University of Massachusetts\, Amherst in 2004. She did he
 r postdoctoral training jointly between the University of Pennsylvania and
  the Cold Neutron for Biology and Technology (CNBT) team at National Insti
 tute of Science and Technology from 2004-2006. She jointed University of C
 alifornia\, Berkeley in both the Department of Material Sciences and Engin
 eering and Department of Chemistry in January 2007. She was promoted to As
 sociated professor with tenure in July 2012.\nHer research interests are t
 o design and fabricate functional materials using polymers\, organic molec
 ules\, nanoparticles\, proteins and peptides via “bottom-up” approache
 s. Researches in Xu's group take advantage of the recent developments in p
 rotein science\, polymer science and nanoparticles synthesis and manipulat
 ion\; and use natural building blocks such as peptides and proteins in con
 cert with the self-assembly of polymer\, conjugated molecule and nanoparti
 cles as platforms to generate nanostructured functional materials. Her res
 earch group focuses on a fundamental understanding of multiple length self
 -assemblies in multi-component systems and aims to generate hierarchically
  structured nanomaterials with built-in biological\, electrical and magnet
 ic functionalities.\nProf. Xu has over 70 peer-reviewed journal articles\,
  5 book chapters and several patents. She is the recipient of several awar
 ds including 2007 DuPont Science and Technology Grant\; 2008 3M Nontenured
  Faculty Award\; 2008 DuPont Young Professor Award\; 2009 Office of Naval 
 Research Young Investigator Award\; 2010 Li Ka Shing Woman Research Award\
 ; 2010 NASA Patent Award\; 2011 Camille-Dreyfus Scholar-Teacher Award\; an
 d 2011 ACS Arthur K. Doolittle Award. She was named as one of “Brilliant
  10” by Popular Science Magazine in 2009.
