research statement

My research focuses on the formulation of new continuum-level constitutive theories for describing material behavior and the quantitative modeling of material behavior through numerical simulation. I am particularly interested in materials that exhibit coupled and size-dependent phenomena.

Some areas of ongoing research include:

1. Constitutive models for granular materials.

2. Simulation techniques for nonlocal models for granular media.

3. Modeling of multi-physics phenomena in soft elastic materials, in particular, dielectric elastomers.
