I am interested in how magma is transported from Earth’s mantle to the surface, as a means of understanding what causes different types of volcanic activity and the processes by which rocks of Earth’s crust are formed. I have led research expeditions to study oceanic spreading centers as well as to volcanic hotspots (Galapagos and Iceland). My group’s current research is to image the magma plumbing pathways in the crust beneath subduction zone volcanoes (Newberry, OR, and Santorini, Greece) by collecting dense geophysical measurements and by doing sophisticated inverse modeling on high performance computers.
- Interaction between hotspot and mid-ocean ridge processes in the mantle, lithosphere, and crust.
- Mid-ocean ridge crustal structure and relationship to mantle processes.
- Volcanic plumbing and eruption.
- Development of seismic methods
- Integrating geophysical, geochemical and geodynamic observations.
- Modeling of physical processes
- Santorini magma plumbing structure (2015 PROTEUS cruise report)
- Newberry volcano magma system and geothermal energy
- Mid-ocean ridge magma and hydrothermal plumbing
- Galapagos crustal and mantle structure
- Cascadia Initiative: An onshore/offshore experiment to study megathrust earthquakes in the Pacific Northwest and also volcanic arc structure, the formation, deformation and hydration of the Juan De Fuca and Gorda plates.
