DESCRIPTION:Fluid anisotropy\, or a direction-dependent response to deform
 ation\, can be observed in biofluids like mucus or\, at a larger scale\, s
 elf-aligning swarms of bacteria. A model fluid used to investigate such en
 vironments is a nematic liquid crystal. Large colloidal particles undergo 
 shape-dependent interactions when immersed in these complex environments\,
  whilst deformable bodies (like red blood cells) tend to be stretched\, of
 fering a passive means of measuring cell material properties. Adding to th
 e complexity are microorganisms that propel themselves through these envir
 onments\, which give rise to active stresses and topological defects\, whi
 ch focus elastic stresses and are important sites in many biological setti
 ngs.\n \nIn this presentation\, we use complex variables to analytically s
 olve for the interaction between bodies immersed in an active liquid cryst
 al. This approach allows for the analytical solutions of a wide range of p
 roblems\, opening the door to studying the role of body geometry\, liquid 
 crystal anchoring conditions\, topological defects\, and activity. Shape-d
 ependent forces between bodies\, local surface tractions\, active stresses
 \, and body deformation will also be discussed.
