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
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.
