Kuiper 515


Renu Malhotra

Regents' Professor, Louise Foucar Marshall Science Research Professor

Astrobiology, Exoplanets; Planetary Formation and Evolution, Orbital Dynamics, Small Bodies, Theoretical Astrophysics

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.

Ph.D., 1988, Cornell University
