DESCRIPTION:Microorganisms swimming through viscoelastic fluids are a comm
 on feature in naturally-occurring fluids. Approaches to modelling this beh
 aviour normally come in two flavours: a macroscale\, course-grained approa
 ch where the fluid is modelled as a continuum\; and a microscale\, detaile
 d approach where the anisotropic structure within the background fluid is 
 specifically modelled. The former approach has the benefit of speed\, but 
 in this talk I will share my experience of attempting the latter\, in 3D\,
  using high-performance computer simulations\, and show how these simulati
 ons suggest the physical structure of the viscoelastic fluid directly affe
 cts the microorganism swimming through it. We see some surprising differen
 ces with 2D and investigate why this might be so.
