Nature uses only the longest threads to weave her patterns, so that each small piece of her fabric reveals the organization of the entire tapestry.

Computational Planetary Dynamics





My students and I perform numerical simulations with gravitational N-body codes to study a wide variety of problems in astrophysics. These have included the middle and late stages of planetary formation, problems associated with the formation of Uranus and Neptune, the rotational evolution of asteroids and planetary satellites, and the orbital evolution of extrasolar systems. Recently, we have adapted our simulation to study other gravitationally bound systems such as stellar clusters.
