DESCRIPTION:The textures and phases of liquid crystals are rep
 lete with geometric motifs\, and the geometric app
 roach to elasticity underpins a large portion of n
 onlinear theories. Despite this\, the basic charac
 terisation of topology comes from the homotopy the
 ory without particular attention to geometric feat
 ures. I will describe our recent work developing g
 eometric approaches to liquid crystal topology\, d
 escribing cholesteric point defects and topologica
 l chirality\, and the geometric features of bend d
 istortions\, illustrated by applications to the tw
 ist-bend nematic phase.
