Research Statement
|
| |
Dr. Hill joined the Rice faculty in 1975. The general area of his research interests is solar-system plasma physics, particularly the magnetospheres of the planets. Research programs in progress include (1) theoretical and numerical modeling of the interaction of Earth's magnetosphere with the solar wind and with the ionosphere, and associated data-analysis efforts, (2) theoretical and numerical study of rotationally-driven convection in the magnetospheres of Jupiter and Saturn, and resulting pulsar-like effects, and (3) comparative study of planetary magnetospheres. He is an active participant in the National Science Foundation's Geospace Environment Modeling initiative (part of the U.S. Global Change Program) to develop a predictive capability for magnetospheric activity. He is also a co-investigator for the Cassini Plasma Spectrometer investigation on the NASA/ESA Cassini-Huygens mission to Saturn and Titan. |
