My group's research focuses on continuum-level modeling of engineering materials. Predictive continuum modeling is a cornerstone of solid mechanics, invaluable in the design of devices and structures and capable of yielding important physical insights. The goals of our research are (1) the formulation of new continuum-level constitutive theories for describing material behavior and (2) quantitative modeling of material behavior through numerical simulation.
Some areas of ongoing research include:
1. Constitutive models for flow and size-segregation in dense granular materials.
2. Large-deformation, viscoelastic constitutive modeling of elastomeric foams.
3. Modeling the dynamics of bubbles in soft solids.
