Geophysics
The focus of my research is to understand the dynamics of
Earth's interior, including both the mantle and the core. I am especially interested in how these two major parts of the Earth interact to
produce plate tectonics, deep mantle plumes, and the geomagnetic field.
My approach is to combine theory, numerical models, and laboratory fluid dynamics models, and to use these
to interpret global geophysical data pertaining to the deep interior.
Lately I have concentrated on the dynamics of Earth's core, particularly the magnetohydrodynamic processes by which the geomagnetic field
is generated in the fluid outer core, and modified by the solid inner core and the lower mantle. This work is being done in collaboration with
colleagues around the world and with graduate students and postdoctoral fellows here at Johns Hopkins.
Examples of my recent research include:
Numerical Models of the Geodynamo
Polar Vortex Motion in the Core
Zonal Winds generation on the Giant Planets
Rotating Convection
