Jacqueline N. Hewitt PhD '86

Julius A. Stratton Professor of Physics
Current research interests are in radio astronomy investigations of the Cosmic Dawn.

Research Interests

Professor Hewitt’s research interests are in the application of techniques of radio astronomy and signal processing to problems in astrophysics. She was one of the pioneers of wide-area radio surveys with the Very Large Array radio telescope, work that led to the discovery of the first Einstein ring gravitational lens. Current topics are low-frequency radio studies of the Epoch of Reionization and the Dark Ages, and surveys of transient astronomical radio emission. She was a founding collaborator in the Murchison Widefield Array project, a low-frequency radio telescope in Western Australia designed to study the Epoch of Reionization. Professor Hewitt is currently one of the lead investigators of a larger array with similar scientific goals,the Hydrogen Epoch of Reionization Array telescope project in South Africa.

Biographical Sketch

Jacqueline Hewitt graduated from Bryn Mawr College in 1980 and received her Ph.D. in physics from MIT in 1986. After postdoctoral appointments at MIT’s Haystack Observatory and at Princeton University, she returned to MIT in 1989 to join the faculty. From January 2002 through January 2019, she was Director of MIT’s Kavli Institute for Astrophysics and Space Research (formerly the Center for Space Research). She is the recipient of the 1993 Booker Prize from the International Union of Radio Science, the 1995 Maria Goeppert-Mayer Award from the American Physical Society (APS), and the 1991 Presidential Young Investigator Award from the National Science Foundation. In 2012, Time magazine named her one of the 25 most influential people in space. She is a fellow of the American Academy of Arts and Science, a fellow of the American Association for the Advancement of Science, a fellow of the APS, a former David and Lucile Packard Foundation fellow, and a former Alfred P. Sloan fellow. Her National Academies service includes chairing the committee that performed the Congressionally-mandated midterm assessment of the 2010 “New Worlds, New Horizons in Astronomy and Astrophysics” decadal survey; she was also the chair of Panel on Particle Astrophysics and Gravitation for the 2010 survey.
