Priyamvada Natarajan

Priyamvada Natarajan is the inaugural Joseph S. and Sophia S. Fruton Professor in Astronomy & Physics at Yale University, with a secondary appointment in Physics. A member of the Yale faculty since 2000, she currently serves as Chair of the Department of Astronomy and, since 2022, as an external Principal Investigator at Harvard’s Black Hole Initiative.

A theoretical astrophysicist, Natarajan works at the confluence of cosmology, gravitational lensing, dark matter, dark energy and black hole physics. Her research has helped illuminate the most profound questions in modern astrophysics pertinent to the invisible Universe: the nature of dark matter & dark energy and the origin and growth of black holes across cosmic time. Using gravitational lensing as a precision tool, she has developed new ways to map the distribution of dark matter and dark energy, advancing our understanding of dark matter substructure and the small-scale architecture of the universe and role of dark energy. She has also been a leading architect of theoretical models for the formation of the first black holes. Her work on the rapid formation of massive black hole seeds—including the formation of heavy seeds from direct gas collapse and from runaway growth in dense stellar environments—offers a compelling framework for explaining how supermassive black holes emerged so early in the universe as well as their continual formation over cosmic time. These ideas are now finding striking observational support from the James Webb Space Telescope and the Chandra X-ray Observatory, whose discoveries are revealing unexpectedly massive black holes within the universe’s first billion years. She is a scientific contributor to several major JWST programs, including NGDEEP, GLIMPSE, and SLICE, all aimed at probing the earliest galaxies and black holes.

Natarajan’s scholarship, comprising more than 350 scientific publications, has had broad influence across astrophysics and cosmology. She is a Fellow of the American Physical Society, the American Astronomical Society, the American Academy of Arts and Sciences, and the American Association for the Advancement of Science. Her honors include Guggenheim and Radcliffe Fellowships, the 2022 Liberty Science Center Genius Award, and the 2025 Dannie Heineman Prize for Astrophysics. In 2024, she was named to the TIME100 list in recognition of her scientific contributions.

Beyond her research, Natarajan has been a prominent leader in astronomy focused on increasing championing dual-anonymous review for telescope time allocation and research funding. Her service has included chairing the National Astronomy and Astrophysics Advisory Committee and the Division of Astrophysics of the American Physical Society; she currently serves on the Scientific Editorial Board of the AAS journals.

She received undergraduate degrees in Physics and Mathematics from MIT and earned her PhD from the Institute of Astronomy at Cambridge, where she was the first woman in astrophysics elected to a fellowship at Trinity College. Her intellectual reach extends well beyond astrophysics: she directs Yale’s Franke Program in Science and the Humanities and is the author of the critically acclaimed Mapping the Heavens: The Radical Scientific Ideas That Reveal the Cosmos. A committed public intellectual, she writes and speaks widely about science, and her collaborations with contemporary artists have been featured at the Venice Biennale and the Guggenheim Museum Bilbao.
