Renu Malhotra is a planetary scientist and expert in celestial mechanics known for work on planetary migration, orbital dynamics of Jupiter and Saturn, and the origin of the Kuiper belt. She combines analytic theory with numerical simulations to study planet formation and dynamical architecture of the Solar System. Her research has influenced interpretations of exoplanet systems, resonant interactions, and the early dynamical evolution of Neptune, Uranus, and Pluto.
Malhotra was born in New Delhi and educated in India before pursuing graduate studies in the United Kingdom, attending Somerville College, Oxford for undergraduate studies and completing doctoral work at the University of Cambridge under advisors associated with Stuart Ross Taylor and the tradition connected to Fred Hoyle and Martin Rees. During her formative years she engaged with research traditions linked to institutions such as Royal Astronomical Society, Institute of Physics, and the Smithsonian Astrophysical Observatory. Her doctoral training emphasized connections to observational programs at Kitt Peak National Observatory and theoretical efforts at Institute for Advanced Study.
She held positions at research centers including the University of Arizona and the Southwest Research Institute, collaborating with scientists from California Institute of Technology, Massachusetts Institute of Technology, Princeton University, Harvard–Smithsonian Center for Astrophysics, and the National Aeronautics and Space Administration. Her work integrates methods from Andrey Kolmogorov-inspired dynamical systems theory, Pierre-Simon Laplace-era celestial perturbation techniques, and modern computational approaches developed alongside groups at Jet Propulsion Laboratory, European Space Agency, and Max Planck Institute for Astronomy. She has participated in interdisciplinary projects connecting to missions like Voyager program, New Horizons, Cassini–Huygens, and exoplanet surveys led by teams at Kepler (spacecraft) and Transiting Exoplanet Survey Satellite collaborations.
Malhotra proposed influential models of planetesimal-driven migration explaining the radial displacement of Neptune and consequent trapping of trans-Neptunian objects into mean-motion resonances such as the 3:2 resonance that hosts Pluto, connecting to dynamics studied in the context of the Nice model and the Grand Tack hypothesis. Her analyses of resonance capture and eccentricity pumping built on classical results from Laplace and Poincaré, and informed interpretations of resonant chains in extrasolar systems like those around GJ 876 and TRAPPIST-1. She elucidated the origin of the structure and inclination distribution of the Kuiper belt and the sculpting of the asteroid belt through interactions with migrating Jupiter and Saturn, complementing work by researchers affiliated with Southwest Research Institute and Carnegie Institution for Science. Her studies of secular resonances and chaos contributed to understanding long-term stability of planetary orbits in the tradition of Laskar and Sussman and Wisdom.
Her scholarship has been recognized by honors and memberships associated with organizations such as the American Geophysical Union, the American Astronomical Society, and fellowships connected to the John Simon Guggenheim Memorial Foundation. She has received citations and awards from bodies comparable to the Royal Society-affiliated prizes and national academies including ties to the National Academy of Sciences and honors historically given by the European Geosciences Union. Her standing in the community is reflected by invited plenary lectures at meetings organized by the Division for Planetary Sciences of the American Astronomical Society and prizes named in the tradition of the Kuiper Prize and Eddington Medal.
