Professor, Earth & Planetary Sciences
Gary develops global three-dimensional time-dependent computer models to study the structure and dynamics of the interiors of planets and stars. The first in this series of models was written in the 1980s to study the solar dynamo. A modified version of this model was used for pre-flight studies and post-flight analyses of a rotating fluid dynamics experiment flown aboard NASA Space Shuttles in 1985 and 1995. In his studies of geodynamics he has simulated global circulation and convection in the Earth's atmosphere, mantle and core. He has also simulated convection and magnetic field generation in the deep interiors of giant gas planets like Jupiter and Saturn.
