A. OVERVIEW

 

** OVERVIEW My research interests are focused on the mechanics and deformation of the Earth's shallow crust. I am interested in deformational processes at convergent margins, relating to sediment accretion and plate boundary seismogenesis. I also study the unique tectonics of oceanic volcanic islands, where magmatic and gravitational forces cause large scale flank collapse and associated hazards. The formation and evolution of fault gouge influences the frictional behavior and mechanical strength of natural and experimental faults. My field studies are coupled with particle based numerical simulations to explore the mechanics of natural systems in the brittle-frictional regime.
