"  Can we hear the distribution of residual stresses in arteries? "
  Sunnie Joshi  


Inverse problems arise in many areas of science and mathematics, including geophysics, astronomy, acoustic tomography and medical biology. Inverse spectral problems is a branch of inverseproblems that has applications in most of these areas and involves reconstructing an operator from its spectral characteristics. Our motivation for studying such problems comes from an application in biomechanics, particularly in estimating material parameters such as stiffness, residual stress etc. of soft tissues. In this talk, we will look at a model on how to reconstruct residual stress field in arteries by making use of intravascular ultrasound (IVUS) imaging techniques.
