DESCRIPTION:Liquid crystals are composed of rod-shaped particles. At high 
 enough density\, they can form long-range orientational order but without 
 positional order. In active liquid crystals\, energy is also injected cont
 inuously to the system by the individual particles. Examples of active liq
 uid crystals include bacterial suspensions and cell cytoskeletons. In this
  talk I will explore some consequences of the this local energy injection 
 such as spontaneous flow transition and spontaneous motility in active dro
 plets. Finally I will discuss the behaviour of a sheared but passive liqui
 d crystal where energy is injected to the system at the boundaries\, inste
 ad of locally. In particular I will show how this may lead to a shear-indu
 ced first order phase transition.
