Ed Rhodes leads an active program in both ground- and space-based
observational helioseismology. One of the pioneers in this field of
solar physics he is a NASA-selected Co-Investigator on the Solar
Oscillation Investigation (SOI). The SOI-Michelson Doppler Imager flys
onboard the NASA-ESA Solar and Heliospheric Observatory spacecraft. Dr.
Rhodes is the Principal-Investigator for the
60-Foot Solar Tower at Mt.
Wilson Observatory and the High Degree Helioseismic Network (HiDHN).
This network onsists of a second station in Ukraine, at the Crimean
Astrophysical Observatory. HiDHN provides nearly continuous
observations of the sun during the summer months. Beginning in 1992 Ed
Rhodes served as a Guest Computational Investigator in the NASA High
Performance Computing and Communication Program. As part of this
program he and his group employed several NASA-supported supercomputers
located at Caltech and at JPL. These computers are still used in
addition to a network of dedicated workstations located both at USC and
the 60 Foot Solar Tower.
