Biography

I am interested in all aspects of the regional geology and tectonics of New Zealand, Zealandia and the SW Pacific Ocean. My main research tools are petrology, mineralogy, geochemistry, geochronology, structural geology and GIS. I have contributed to several advances in New Zealand’s regional geology, including Otago Schist architecture, the Median Batholith, subdivision of greywacke terrane basement, long baseline evolution of volcanic arcs north of New Zealand, a holistic high-level stratigraphy of New Zealand rocks, and exploration and promotion of Earth’s eighth continent, Zealandia. I have a broad working knowledge of Zealandia’s igneous, metamorphic, sedimentary and tectonic makeup, and its 500 million year geological history. Consultancy work and outreach are an important part of my professional life at GNS Science.
