About
I am a structural geologist primarily interested in the interplay between rock deformation, fluid flow, and geochemical reactions. I focus on coseismic fault rocks, the rheology of heterogeneous shear zones, and factors controlling brittle-ductile transitions in crustal rocks. My methodologies include detailed field mapping, microstructural studies, mathematical modelling, and geochemical techniques such as stable isotope analyses, X-ray diffraction, X-ray fluorescence, and mineral chemistry determined by the electron microprobe. My recent research has been aimed to advance understanding of subduction zone fault processes, in particular the geological factors that may control styles of active deformation, such as the partitioning of seismic and aseismic slip on the subduction megathrust. Determining the physical processes behind the recently discovered seismic phenomena of episodic tremor, very low frequency earthquakes, and slow slip, is another ongoing interest.
