The effective strength of oceanic plate bounding faults
Principal Supervisor: Dr Craig O’Neill
Associate Supervisor: Dr Sandra Piazolo
I am working towards my PhD in Geodynamics, aiming to develop robust rheological models to predict the long-term geodynamic response of oceanic faults. This will result in combining the weakening mechanisms which are dependent on strain accumulation, strain rate, and alteration processes. My project is classified into the following three major parts:
1) Constrain the serpentinization of plate-bounding oceanic faults, via combined geophysical, petrological and geodynamic modelling.
2) Incorporate these derived alteration patterns and their associated rheological laws into geodetically constrained geodynamic models to understand the way alteration processes impinge on the behaviour of oceanic faults.
3) Apply this combined, iterative approach to a number of sample sites around the Australian plate to understand the propagation of stresses into the interior of the plate and the detailed microdynamics of Australia’s tectonic boundaries.

I received my M.S from Department of Geology, California State University Northridge (CSUN), USA, in 2012. I have also earned my B.Sc. and M.Sc. degrees in geology from University of the Punjab, Lahore, Pakistan. My M.Sc. thesis at CSUN focuses on the paleoseismology of the San Gorgonio Pass Fault zone (San Andreas fault system) near Cabazon, California with Dr J. Douglas Yule.
Apart from my work life, I have interests in a number of outdoor activities which include hiking, mountain biking, taking part in adventures and of course, enjoying the beautiful combinations of oceans and forests around Sydney.
