My research focuses on computer modeling of deformation in solid materials with an emphasis on geomaterials such as rocks, soils, and concrete, as well as biomaterials. In particular, I use finite element analysis to investigate a variety of problems, from plasticity and damage to fracture, shear banding and other types of localized deformation. Current areas of interest include:

Evolving discontinuity methods for capturing fracture, shear banding, and other forms of localized deformation

Coupled-physics problems, such as couple mechanics and fluid flow in soil biological tissues, and therm-hydro-mechanics of geothermal heat pumps

Computational plasticity, damage and constitutive modeling for geomaterials and soft tissues

Finite elements and other computational techniques

Structural behavior of earthen structural material such as rammed earth and stabilized soil block

Rail geotechnics
