Professor Malhotra's research spans orbital dynamics in the solar system and in exo-solar planetary systems. Current topics of research are: the orbital migration history of the giant planets, chaos and stability in the Kuiper belt, dynamics of near-Earth and main belt asteroids, the meteoritic bombardment history of the terrestrial planets, and architectures of exosolar planetary systems.

Current Grants
