Roger J. Phillips
Professor Emeritus
Ph.D., University of California at Berkeley, 1968

Professor Phillips is interested in the interior
evolution of the terrestrial planets and how a planet's evolution affects
and modifies its outer rigid shell or lithosphere through magmatic and
tectonic activity. In this research, a variety of geophysical and geological
data sets are used in conjunction with computer modeling of physical
processes. The underpinning of this activity is application of the concepts
of continuum mechanics, with emphasis on computational fluid and solid
dynamics, to a variety of geodynamical environments (convection and Stokes
flow in viscous fluids, surface and subsurface water flow, elastoviscoplastic
deformation of the lithosphere). A variety of approaches are employed,
including analytical and numerical methods, and the solid mechanics finite
element package MARC©.
Professor Phillips is retired from Washington University
but continues to be active as a scientist at the Southwest
Research Institute in Boulder, Colorado.
