Interests:

  • Computational multiscale mechanics for porous and particulate materials.
  • Mechanics of single phase (dry) and multiphase (partially-saturated and saturated, multi-constituent) porous materials, such as geomaterials (soil, rock), concrete, and soft biological tissues.
  • Damaged polycrystalline metals.
  • Generalized continuum theories for multiscale modeling of inelastic deformation.
  • Applications include modeling geotechnical, geological, and structural engineering failures, high strain rate loading of polycrystalline metals and soils, and visco-poroelastic response of ocular tissues and other biological tissues.
