August 2020 - Present: Assistant Professor of Geology and Geophysics at the College of Earth, Ocean, and Atmospheric Sciences, Oregon State University. My group focusses on the time-dependent state of structure and strain along the western North American plate boundary, especially in regions where significant geohazards (e.g., earthquakes, volcanoes) exist. To achieve that aim, we use multiple traditional and more modern (e.g. Large-N array seismology, UAV and space-borne data, artificial intelligence) geophysical tools to image and monitor structure at mostly crustal depths. We also explore the complementary nature of seismic, electrical, electromagnetic and geodetic methods and how these tie into results obtained from geological mapping at the surface. These geoscientific "puzzle pieces", assembled properly, provide us with a more holistic understanding of the active Earth.
August 2018 - July 2020: Green postdoctoral scholar at the Institute of Geophysics and Planetary Physics, SIO, UCSD. My postdoc work focussed on structural properties of the two major faults accommodating most of the plate motion in southern California, the San Jacinto and southern San Andreas. This system of faults is building up to large earthquakes, and I studied them using electromagnetic and seismic tools to reveal conditions prevalent during this late deformation phase.
August 2013 - July 2018: PhD in Geophysics at the University of Southern California. My research at USC revolved around using large seismological datasets to image and study fault zones at multiple length scales. The knowledge gained from this work has helped improve our understanding of fault zone material properties and the significant role they play in the physics of earthquake faults and rupture. This, in turn, has significant implications for seismic hazard estimates.
June 2011 - July 2013: Full-time employee at the Council for Scientific and Industrial Research, South Africa, working as a researcher in mining seismology and applied geophysics. The seismological research involved studying the state of deformation and stress associated with mining induced seismic events, while in applied geophysics, I studied the application of geophysical tools such as borehole radar (BHR) and electrical resistivity tomography (ERT) to mining exploration and planning.
August 2008 - December 2012: Completed my MSc degree with a dissertation entitled “Prediction of DC current flow between the Otjiwarongo and Katima Mulilo regions, Namibia”. My advisors were Prof. Alan G. Jones (now at Complete MT solutions, Canada) and Dr. Susan J. Webb (University of the Witwatersrand, South Africa) and the research part of the degree was done at the Dublin Institute for Advanced Studies (Ireland). My research focused on high resolution studies using magnetotellurics (MT) and audio-magnetotellurics (AMT) in northern Namibia, to firstly aid in the optimal placement of two High-Voltage Direct Current (HVDC) Earth electrodes, and secondly, to try to predict the return flow of DC current within the ground between the two electrodes. The study included a fieldwork component which was completed between February and June 2008, where MT and AMT data were acquired at various locations in Namibia, Botswana and South Africa.
June 2009 - July 2009: Participated in the Summer of Applied Geophysical Experience (SAGE) program in New Mexico, USA.
January 2007 - December 2007: Acquired my BSc Honours degree in geophysics at the University of the Witwatersrand. The fieldwork aspect of the degree was completed through participation in the AfricaArray field school and my final year project was entitled “Dynamic and Quasi-static Deformations of the Rocks Derived from Underground Seismic and Tilt data”.
January 2004 - December 2006: Completed my BSc degree at the Nelson Mandela University, South Africa, majoring in Physics and Geology.
