RESEARCH INTERESTS
Richard Greenberg is Professor of Planetary Sciences at the University of Arizona. He leads an active research program in planetary science at the University of Arizona, where he and his research team carry out investigations of the dynamical evolution of the solar system, including studies of asteroids, meteorites, planetary rings, planetary formation, and extra-solar planets. He has had a long-term research program, dating back to his doctoral dissertation, in tidal processes and orbital resonances among natural satellites, and their implications for the history and physical character of the satellites. Greenberg served as a member of the Imaging Team for NASA's Galileo spacecraft, where his research began to focus on characterizing and interpreting Jupiter's satellite Europa, which formed the basis for his two books on Europa.

From 1989 to 2001 Greenberg led the University of Arizona's campus-wide initiative in support of pre-college science, mathematics, and technology education as founder and director of the Science and Mathematics Education Center. Accomplishments include reform of the teacher-preparation program, unique new procedures for appropriate evaluation and reward for faculty efforts in education, cultivation and coordination of sponsored projects across the campus, and integration of the K-12 science and mathematics teaching communities into the education activities of the University. Greenberg founded and directed the Image Processing for Teaching (IPT) project, which gave students in classrooms across the nation the power to engage in substantive scientific exploration and discovery using state-of-the-art digital image processing.
