MSE Areas: Geomaterials, soft biological tissues, multiscale multiphysics computational mechanics, thin deformable porous materials, particulate materials
Computational modeling of the mechanics of porous and particulate materials is the focus of my research program at CU Boulder. Ever-increasing computing power and highly-resolved experimental laboratory observations afford the use of computational multiscale multiphysics materials modeling in engineering analysis and design. Physical processes such as granular material interaction with a tool or tire, buried explosive loading of soils, soil-structure interaction in energy foundations, performance of solar photovoltaic (PV) asphalt pavements, or ocular lens accommodation and traumatic cataract formation can now be better understood with computational multiscale multiphysics materials modeling. My research program establishes collaborations with experimental laboratory scientists and engineers who can probe the mechanics of materials at various length and time scales, to assist in developing, improving, and applying the multiscale multiphysics computational models to harness the observed phenomena.
