Research Interests:

Research interests

I am interested in all aspects of the dynamics of planetary systems, from the orbital evolution of dust particles to the stability of planetary orbits. My research in recent years has been dominated by work on Saturn's rings and their gravitational interaction with the small natural satellites orbiting nearby. In particular I have been fascinated by Saturn's F ring as I work with colleagues to understand its bizarre appearance. I have been a member of the Imaging Science Subsystem Team on the Cassini-Huygens mission to Saturn and I have worked on the project since I was selected in 1990.
