Current research interests

Fracture, Friction and Flow

The geometry, kinematics and processes of deformation form the core of the research program, with special emphasis on application of electron-beam techniques to microstructural and microchemical studies. Transmission electron microscopy forms a significant component of the research.

Large-scale fault zones commonly act as study areas, with projects along the Minas fault zone, Nova Scotia, and the Denali fault system, Yukon. Microstructural studies from various fault zone drilling projects currently include the San Andreas Fault (SAFOD), the Alpine Fault, NZ (DFDP) and plate margin megathrust of the Tohoku-Oki earthquake, Japan (JFAST).
