Ken Rice

Welcome to my webpage at the University of California, Riverside, where I am an Assistant Professor of Astrophysics in the Department of Physics and the Institute of Geophysics and Planetary Physics. My research interest is primarily the evolution of accretion discs and how this relates to aspects of star and planet formation. I am particularly interested in accretion discs that are massive enough for self-gravity to play a role in their evolution.
