Summary
Glen Stewart develops models of the formation of planetary systems, including planetesimal dynamics, hydrodynamic instabilities in the dead zones of protoplanetary disks, and the formation of the regular satellites of Jupiter and Saturn. He is also an expert on the dynamics and evolution of Saturn's rings and has been involved in the study of ring observations made by the Cassini spacecraft.
