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
