# David Spergel

David Nathaniel Spergel is an American theoretical astrophysicist and the Emeritus Charles A. Young Professor of Astronomy on the Class of 1897 Foundation at Princeton University. Since 2021, he has been the President of the Simons Foundation. He is known for his work on the Wilkinson Microwave Anisotropy Probe (WMAP) project. In 2022, Spergel accepted the chair of NASA's UAP independent study team.

## Early life and education

Spergel was born to a Jewish family in Rochester, New York. His father, Martin Spergel, was also a physicist and a professor at York College, City University of New York; he died in 2021. His mother was a high school home-economics teacher. The junior Spergel attended John Glenn High School in Huntington, New York. He has a brother and a sister.
Spergel graduated summa cum laude with a Bachelor of Arts (AB) from Princeton University in 1982, after completing a senior thesis on red giants under the supervision of Gillian R. Knapp. He then went to the University of Oxford as a visiting scholar in 1983, where he studied with James Binney. He obtained his Master of Arts (AM) in 1984 and his PhD in 1985, both from Harvard University.

## Career

At the invitation of John N. Bahcall, Spergel joined the Institute for Advanced Studies after his PhD. He left and moved to Princeton University in 1987 as an assistant professor. He was promoted to associate professor in 1992 and full professor in 1997. In 2007, he was appointed the Charles A. Young Professor of Astronomy on the Class of 1897 Foundation.
Spergel joined the Flatiron Institute in 2016 as the founding director of the Center for Computational Astrophysics. Citing the hesitance to hold onto 2 positions, he retired from Princeton University in 2019 at the age of 59, and has remained as emeritus professor since.
Spergel is a 2001 MacArthur Fellow, and was a member of the NASA Advisory Council and chair of the Space Studies Board. He was the Keck Distinguished Visiting Professor at the Institute for Advanced Study from 2000 to 2001.
Since 1994, Spergel is part of the Wilkinson Microwave Anisotropy Probe (WMAP) project consortium. Currently, he is a member of the Simons Observatory, chairs the Science Definition Team of the Nancy Grace Roman Space Telescope (formerly known as the Wide-Field Infrared Survey Telescope), and sits on the Board of Trustees of the Carnegie Institution for Science (since 2022).
In 2022, Spergel was invited to lead NASA's UAP independent study team of sixteen members to provide guidance in better understanding "unidentified anomalous phenomena".
