Research interests

I am a postdoctoral research fellow based at the Research School of Earth Sciences, Australian National University, Canberra. My research focuses on mantle/experimental petrology, geothermobarometry and diamond exploration. My research aims to improve the understanding of the lithospheric architecture, mantle lithology and geochemistry of the Australian continent using mantle xenoliths and kimberlite indicator minerals recovered from diamond exploration programs. I have two current projects focused on the mantle beneath the Kimberley Craton of north-western Australia and the Phanerozoic Tasmanides of eastern Australia, as well as several smaller projects on new kimberlite discoveries acorss Australia and geothermobarometry related projects. In addition to current research, I also have a broad interest in high-temperature geochemistry, igneous and metamorphic petrology, and mineral exploration.
