Edmond C. Roelof has been involved in space plasma physics since 1966 with over 200 published papers in the areas of energetic particles, plasma, magnetic fields, and radio emissions throughout the solar system: in the solar corona, the interplanetary medium, and the magnetospheres of Earth, Jupiter, and Saturn. He continues these investigations as a co-investigator with the JHU/APL experimenter teams on the NASA Ulysses (heliosphere), Galileo (Jupiter), ISTP (Geotail), and Cassini (Saturn) missions. He is an acknowledged leader in the emerging field of magnetospheric imaging; he will participate in the first two NASA missions, IMAGE and TWINS, as well as the ESA Mars Express Mission.
