My research interests are focussed on submarine volcanic and magmatic processes, marine geohazards and blue resources and energy. I use a variety of techniques (including marine geophysical surveying, X-ray computed tomography, scanning electron microscopy and geochemistry) and work with cutting edge technologies (marine remotely controlled and autonomous platforms) to investigate the mantle to surface processes that build our planet. I currently lead the NERC funded Tonga RAFTS project investigating shallow submarine volcanic processes in the Tofua Arc and contribute to others looking at seafloor resources and hazards.
