Richard H. Durisen (b. 1946), on the faculty of Indiana University, has applied dynamical simulations to star and planet formation, the structure and stability of astrophysical disks and planetary ring systems, and he has used numerical hydrodynamics techniques to study gravitational instabilities in disks around young stars.
