Research Profile:
My research focuses on developing new insights into the mechanical behaviour of faults and the tectonics of the lithosphere. I am particularly interested in how fault behaviour effects geological processes such as mountain building, rifting and volcanism. My specialism is in using a wide range of observational techniques from geomorphology, space-borne satellite geodesy (InSAR, GPS), seismology, potential field analysis, paleoseismic trenching and structural geology, and combining these observations with numerical modelling, to study both active and ancient fault zones.
Current areas of interest are:
- Measuring the frictional mechanics of active faults
- Linking geophysical inferences of fault mechanics with fault zone geology
- Tectonics and dynamics of mountain ranges, rifts and subduction zones
- Mapping historically active faults and estimating seismic hazard
If you are interested in working on one of these topics for a PhD/Masters degree – get in touch
