Research interests:
1) Arc settings – evaluating volatile budgets and estimating absolute fluxes of various volatile
species (Central America, the Northern Mariana Islands and the Izu Islands)
2) Back-arc basins – assessing the relative contributions of slab, crust, hotspot and upper mantle
components to the magma source (the Manus Basin)
3) Submarine volcanic systems – using hydrothermal fluids and basaltic glasses to understand the
degassing process as well as determine the provenance of different magmas (the Manus Basin,
the Reykjanes Ridge, Pitcairn seamounts, Loihi Seamount, the Alarcon Basin, Mariana crosschain seamounts)
4) Volatile fluxes – estimating volcanic emissions using remote sensing and geochemical techniques
5) Magmatic degassing – evaluating the effects of composition, water content and eruption depth
