Geodynamics of Earth's Lithosphere and Mantle
|
My research is
directed toward gaining a better understanding of the Earth's dynamic
interior, with a focus on the mantle, which convects slowly over
millions of years, and the lithosphere, which is broken into several
tectonic plates that move in response to mantle flow. I accomplish this
using three-dimensional, time-dependent, numerical models of mantle
flow that can be constrained using geological and geophysical
observations. Such constraints stem from a variety of geoscience
disciplines and include observations such as Earth's surface
topography, tectonic plate motions (both past and present), patterns of
seismicity at plate boundaries, and direct observations of mantle flow
made using seismic tomography or seismic anisotropy. When compared
against predictions made using numerical models of mantle flow, these
geological and geophysical observations reveal the dynamical workings
of our planet's active interior, and its influence on our surface environment. |
