  • Catchment erosion response to climate change over the last glacial cycle. How does the landscape respond/adapt to climate change?
  • Soil production and erosion. Combined use of uranium-series and cosmogenic isotopes to study the controls on the evolution of weathering profiles and soil resources
  • Sediment production and transport. How fast are sediments produced, stored and exported? Study of small and large catchments under various climates (semi-arid to temperate southeastern Australia, tropical Puerto Rico)
  • The production of silicic magmas. Study of the mechanisms and rates of magma evolution in the crust and how they relate to eruptive styles

  • highly depleted lavas and deposits of Tofua Volcano (Tonga Arc)
  • insight into timescales of magmatic processes such as melt generation, differentiation and transport
  • using U-series disequilibria, primarily high resolution 226Ra/230Th disequilibria
  • This approach aims to minimise the heterogeneity in subduction conditions encountered when studying at the inter/intra-arc scale
