Avalanches in Granular Materials: Mean Field Theory

Analytical derivation of hysteresis behavior and stability analysis of granular assemblies in rotating drums. Predicted a logarithmic divergence in avalanche lifetimes close to the transition to continuous granular flow (currently under experimental investigation).

Dynamics and Avalanches in Granular Materials: Experiments

First avalanche imaging study: obtained evidence of scaling behavior when a granular assembly is slowly driven to the threshold of instability. Characterized the dynamics of the precursor avalanches prior to large slides.
