DESCRIPTION:Liquid crystals (LCs) are anisotropic\, viscoelastic fluids th
 at can be used to direct colloids into organized assemblies with unusual o
 ptical\, mechanical\, and electrical properties. In past studies\, the col
 loids have been sufficiently rigid that their individual shapes and proper
 ties have not been strongly coupled to elastic stresses imposed by the LCs
 . We will discuss how soft colloids (micrometer-sized shells) behave in LC
 s. We reveal a sharing of strain between the LC and shells\, resulting in 
 formation of spindle-like shells and other complex shapes. These results h
 int at previously unidentified designs of reconfigurable soft materials wi
 th applications in sensing and biology. Also to be discussed: related effo
 rts relevant to biolocomotion and an immersed boundary method for computin
 g fluid-structure interactions in a nematic liquid crystal.
