Isotopic geochemistry (stable and radiogenic isotopes)
Kimberlites and related rocks (petrogenesis, melt inclusions)
Mantle petrology (Mantle fluids/melts)
My main research activity focuses on the compositions and sources of mantle fluids and low-degree mantle melts including kimberlites and carbonatites. With my work I aim to improve our understanding of the evolution of the Earth’s mantle and the melting processes affecting it with particular attention to the role of volatiles and recycled crustal material as triggers of melting events. To achieve these goals I combine detailed textural, petrological and melt inclusion studies of mantle and igneous rocks with measurements of major-trace element concentrations and radiogenic and stable isotopic compositions using state-of-the-art analytical techniques (e.g., field-emission SEM, micro-Raman, single and multi-collector ICP-MS, SIMS, noble-gas mass spectrometry).
In 2015 I established the Kimberlites and Diamonds (KiDs) research group (co-led by Prof David Phillips), which is based at the University of Melbourne, but counts numerous collaborations with other Australian institutes (University of Tasmania, Australian National University, Macquarie University, University of Western Australia) and industry partners (De Beers, Anglo-American). The group currently includes 11 postgraduate students and explore a range of research topic from the petrogenesis and geochronology of kimberlites and related rocks to the isotope geochemistry of metasomatised mantle rocks.
