I am a seismologist and marine geophysist. My research has developed along four major lines: ocean-bottom seismometer and marine geophysical studies of oceanic crust and upper mantle, isostasy of continents and oceans, lateral heterogeneities and azimuthal variations in seismic velocity in the mantle related to convection, and the dynamics of mid-ocean-ridge tectonics.
I majored in physics at Grinnell College. My graduate studies took place at the Woods Hole Oceanographic Institution/MIT Joint Program, focusing on marine geophysics and seismology. After three years of post-doctoral research at Lamont-Doherty Geological Observatory of Columbia University, I came to Brown as an assistant professor at the end of 1976 and have been here ever since. My interests are in the processes that create new seafloor at mid-ocean ridges, the properties of the lithosphere and asthenosphere, and the nature of small-scale convection beneath tectonic plates.
I am one of four geophysics faculty in the department. I was coordinator for the seismological phase of a project, the Mantle ELectromagnetic and Tomography (MELT) Experiment, that involved investigators from seven institutions across the country. I am currently chief scientist of the GLIMPSE (Gravity Lineations, Intraplate Melting, Petrology and Seismology Expedition) project which is exploring the origin of some enigmatic volcanic ridges in the Pacific Ocean that are clearly not of hotspot origin, yet are formed in the plate interior west of the East Pacific Rise.
