Research interests

My primary research interest includes investigating how oceanic transform faults generate seismicity along their lengths and how they partition strain into seismic and aseismic slip. 

Thesis

Geometry, Deformation Mechanisms, and Seismic Style of Oceanic Transform Faults

Onland transform faults are well studied due to their relative ease of access, however, their oceanic counterparts, oceanic transform faults are comparatively less well studied. Oceanic transform faults display complex along strike and down dip variability in their ability to generate earthquakes. This variability is believed to be controlled by local variations in material properties, fluid pressure, and small scale geological complexity. Thermal models and remote geophysical data cannot be used to resolve these complexities and hence result in the overestimation of earthquakes compared to observed seismicity. 


The Southern Troodos Transform Fault Zone (STTFZ) in Cyprus, is an excellently preserved example of a Cretaceous oceanic transform fault. Using field observations, mapping and comparing natural fault rocks to experimental studies, this study aims to investigate the ability of oceanic transform fault to generate earthquakes along their strike and down dip.


Ultimately, through studying the complex geometry of the SSTFZ and variations in fault rocks and deformation mechanisms, the seismic hazard of these important plate boundaries can be better understood.
