I study how magma is transported from Earth’s mantle to the surface at volcanoes and the interaction of mantle plumes with ocean ridges. I also investigate the structures that control rupture segmentation at the Cascadia subduction zone. I lead research expeditions to the Cascadia margin, oceanic spreading centers, and volcanic hotspots. I collect and analyze dense geophysical data and use inverse modeling on high performance computers.
