Dr Isobel Yeo

Biography

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 several projects looking at submarine volcanic processes and have senior roles on others covering monitoring of seafloor mining activities, marine pollutants, marine geohazards and mid-ocean ridge volcanism.
