Research interests

During a hiking trip many years ago to the site of the Mt. St. Helen's volcanic eruption, I was first exposed to indications of activity in the Earth's interior. My curiousity and interest in solid Earth geophysics has grown through continued research using techniques in seismology and geophysical fluid dynamics. I am particularly interested in evolutionary processes for continental lithospheric formation, marine geophysical study of oceanic mantle dynamics, intraplate volcanism, and hotspot-ridge interactions, as well as whole mantle convection problems for the Earth and other planets. Observations from seismology, geochemistry, and geological studies are vitally intertwined with theoretical and geodynamic modeling and these interdisciplinary fields can help constrain complex geological systems.
