U-Th-Ra constraints on timescales of magma formation, transport and storage at island arc and intra-plate volcanoes
210Pb-226Ra disequilibria in volcanic rocks
Hf and O isotope ratios of volcanic rocks
The geodynamic evolution of arc systems and geochemical constraints on sub-volcanic structure
Sediment residence time and landscape evolution in semi-arid Australia
Improving our understanding of the use of U-series isotopes in landscape evolution studies: new analytical methods
Using U-series isotopes to look at volatile movement within the magma system (i.e., 210Pb).
Using techniques such as SHRIMP SI and FTIR to determine the water content of pyroxenes from mantle and volcanic rocks. This data is used to estimate the volatile budget of the mantle through determining volatile inputs at subduction zones through to volatile loss by volcanism.
Constraining factors that fractionate U-series isotopes within the erosional environment of the Earth’s crust.
Understanding the petrogenesis of island arc volcanoes, including source components and differentiation processes, through geochemical means including major and trace elements and Sr, Nd and U-series isotopes.
Investigating the timescales of magmatic processes, including magma formation and magma chamber residence times, using U-Th-Ra isotopes.
Resolving the eruptive history of active volcanoes in the south-west Pacific, through examination of their geological record.
Integrating geochemistry and volcanology to understand the influence of magmatic processes on eruptive behaviour.

Volcanology and Pre-eruptive magma storage conditions of East Javanese volcanoes.
Elucidating the driving forces of effusive and explosive activity at Kelud Volcano using a combination of field studies combined with geochemical and petrological techniques, with the aim of investigating changing magma storage, ascent and eruption conditions associated with the two eruptions.
