Description:Bio:  Dr Asaph Widmer-Cooper is an Associate Professor in the
  School of Chemistry at the University of Sydney\, a Chief Investigator of
  the ARC Centre of Excellence in Exciton Science\, and a member of the Uni
 versity of Sydney Nano Institute. His research focuses on the application 
 of computer simulations to understand the formation and properties of nano
 materials. This includes work on colloidal interactions and assembly\, the
  structure and dynamics of complex fluids\, crystal nucleation and growth\
 , and the design of new materials for harnessing solar energy.\n\nAbstract
 :  One of the biggest challenges of the 21st century will be our transiti
 on away from a reliance on fossil fuels to power the world. This will requ
 ire new methods of generating and transforming energy\, involving material
 s with clever design of light-matter interactions. Equally important is to
  make these materials via scalable\, energy-efficient processes\, so that 
 new technologies can be deployed at scale with low embodied energy. This\,
  in turn\, will require better control over the spontaneous\, bottom-up or
 ganisation of atoms\, molecules and nanoparticles into ordered structures 
 at near-ambient conditions.\n\nIn my presentation\, I will discuss how we 
 are addressing this problem\, in collaboration with experimental partners\
 , via the use of theoretical modelling and computer simulations. This will
  include discussion of how nanoparticles interact with each other in solut
 ion [1-4]\, how they can be driven to assemble into optically anisotropic 
 materials [5-6]\, and of how the microstructure of printable perovskite se
 miconductors depends on their interaction with light [7].\n\n 	Kister\, T.
