Interests:

My group aim to tackle some of the challenging direct and inverse problems in engineering mechanics involving wave motion. Examples include:

  • inverse scattering in complex or unknown domains
  • linear/nonlinear wave propagation in materials with periodic, random, or multiphase microstructure e.g. metamaterials, damage/degradation zones, porous/granular media
  • elastic-wave cloaking
  • nonlinear and multi-scale dynamics of material interfaces
