Aug-Dec 2008 Postdoctoral Researcher, University of Wisconsin-Madison and Texas A&M University, USA. Jan-July 2008 Lecturer, University of Otago. 2005-2007 Teaching Assistant, University of Otago, NZ. 2003 Teaching Assistant, Monash University, Australia 2001-2002 Engineering Geologist, Fraser Thomas Ltd., Auckland, NZ. 1999-2000 Research Assistant, Engineering Geology Ltd., Auckland, NZ. 3. Research/professional speciality Structural geology and tectonics: I study localisation in faults and shear zones throughout Earth’s lithosphere; rheology of geological materials; SW Pacific tectonic plate motions; paleoseismology and landscape evolution, and geo-resource sustainability. Methods: I make field observations, undertake microtextural analysis, particularly by electron beam, and synchrotron methods, perform deformation experiments, and validate results by computational models.

  • Otago Geologists Help Probe Alpine Fault's Secrets 27 January 2011
    Otago geologists help probe Alpine Fault's secrets 27 January 2011 As drill core is extracted from the borehole, it is cut into 1m lengths and analysed on-site before being taken to the University of Otago for further study, storage, and distribution to overseas collaborators. Researchers at GNS Science, the University of Otago, and Victoria University of Wellington are coordinating the project, in collaboration with colleagues at The University of Auckland, the University of Canterbury, Liverpool University in Britain and the University of Bremen in Germany. Scientists from the United States and Canada are Brett Carpenter (Penn State University) and Dr Virginia also participating. Toy (Otago) with a drill core that contains the Alpine Fault. Otago Department of Geology researcher Dr Virginia Toy is co-ordinator of the working group undertaking drill-core-sample recovery and logging, while colleague Dr Andrew Gorman is co-ordinating (PhysOrg.com) -- University of Otago geologists a seismic surveying project, using explosives, along are part of an ambitious project currently drilling a 6.5km-long section of the Whataroa Valley, to two boreholes into New Zealand's Alpine Fault to gain a clearer picture of the Fault structure to a learn more about how large faults evolve and how depth of up to 5km. they produce earthquakes. More information: Project updates can be The boreholes will be about 130m to 200m deep viewed at: wiki.gns.cri.nz/DFDP/DFDP-1_Ga … and up to 60m apart at Gaunt Creek near P-1_Progress_Reports Whataroa, north of Franz Josef on the West Coast of the South Island.
