Rick Greenberg began his career at LPL in 1986 as a Senior Research Scientist before becoming a Professor in 1990. His research has centered on investigations of the dynamical evolution of the solar system, including studies of asteroids, meteorites, planetary rings, and the formation of the planets. Rick has had a long-term research program in tidal processes and orbital resonances among natural satellites, and their implications for the history and physical character of the satellites. Recent work has included studies of the tidal evolution of extra-solar planets and the implications for planetary-system formation and planetary properties. Greenberg was a member of the Imaging Team for NASA's Galileo spacecraft mission from 1977 until 2003, where his research became focused on characterizing and interpreting Jupiter's satellite Europa. This work led to the publication of
Randy Jokipii has spent the majority of his professional career at LPL—over 40 years. Prior to joining LPL as a full professor in 1973, he was on the faculty at both the University of Chicago and Caltech. He is one of the world’s leading theoreticians on the study of cosmic rays in the Galaxy and solar system. He is responsible for many of the field’s current paradigms including the origin of the 22-year cycle in the intensity of galactic cosmic rays seen at Earth. Professor Jokipii has had very broad research interests at LPL including cosmic-ray astrophysics, solar, heliospheric and astrophysical plasma physics, plasma and magnetic field turbulence in astrophysical fluids, and the acceleration of charged nuclei to high energies by astrophysical shock waves. He has had formal involvement in a number of spacecraft missions, including Ulysses as an Interdisciplinary Scientist, and as a Guest Investigator for both the Advanced Composition Explorer mission and Voyager Interstellar Mission, the latter of which he remains actively involved.
