Distinguished Astronomer
Marc Postman headshot

Marc Postman is a distinguished astronomer at the Space Telescope Science Institute. Dr. Postman’s background is in observational astronomy. He attended the Massachusetts Institute of Technology, receiving a B.S. in Physics in 1981. He received his Ph.D. in Astronomy from Harvard University in 1986. After receiving his Ph.D., he accepted a 3-year postdoctoral fellowship at Princeton University’s Department of Astronomy. In 1989, he joined the scientific staff at the Space Telescope Science Institute, where he has been ever since.

Dr. Postman’s primary research interest has been the formation and evolution of structure in the universe, from galaxies to the largest superclusters. He was a member of the science investigation team for the Advanced Camera for Surveys instrument that was deployed on the Hubble Space Telescope in 2002. Recently, Dr. Postman lead an international team of researchers to conduct a 4-year survey with the Hubble telescope to study dark matter in galaxy clusters and to detect some of the most distant galaxies in the universe. Dr. Postman was the Principal Investigator for a NASA concept study on the next generation space telescope known as ATLAST and is currently a team member of a follow-on NASA study for the Large Ultraviolet-Optical-near Infrared Space Telescope, called LUVOIR. LUVOIR will be able to search for and detect signs of life in the atmospheres of dozens of exoplanets as far away as 100 light years. Dr. Postman has published over 175 refereed research articles.
