DESCRIPTION:The cell cytoskeleton\, consisting of filaments and molecular 
 motors (such as actomyosin)\, can be modelled as a polar or nematic active
  gel. Here a cell embedded in a surrounding medium is modelled as a drop o
 f active gel. Motility of the model cell depends on flows of the contracti
 le active gel. I will present analytical calculations of velocity fields f
 or different polarisation fields and boundary conditions in two and three 
 dimensions. These solutions will be compared to numerical simulations in w
 hich the approximations required for analytical tractability are lifted an
 d steady state polarisations and velocities can be found. Generic features
  of persistent motion will be discussed and comparisons to available exper
 imental data made. \n\nCo-author: Carl Whitfield (University of Sheffield)
