Research Interests

Resonant Ultrasound Spectroscopy: RUS is an elegant experimental method for determining the full elastic tensor of a single crystal. Elastic constants are a measure of the interaction of the atoms in the crystal lattice and so are sensitive to phase transitions.  We specialize in small sample RUS and thin film RUS in which the elastic constants for a thin film on a substrate can be obtained.
Dynamic problems in continuum mechanics: Using high speed video, I have studied the buckling of a thin rod impacted by a projectile ~ a fancy way of breaking pasta!   We have also studied the dynamics of how a rigid rod moves through a viscoelastic gel including transitions from fluid-like flow to solid-like tearing.
