Dr. Kenneth Sembach became Director of the Space Telescope Science Institute (STScI) in October 2015. In taking over the 600-person institute responsible for the science operations of Hubble Space Telescope (HST), as well as the future mission and science operations of its successor, the James Webb Space Telescope (JWST), Sembach said, "I am delighted to serve the Institute and AURA in this new role. I look forward to keeping STScI at the forefront of astrophysics and enabling revolutionary science for NASA and the nation in the coming years."
In 2009 the Hubble Space Telescope was finally serviced for the last time, and the Institute played a key role in the science priorities of that mission. The science productivity of HST subsequently increased beyond its already unprecedented level: the science community exploiting both Hubble’s new science capabilities and the Hubble Legacy Archive run by STScI. The Institute today is also deeply engaged in preparing for the science operations of the James Webb Space Telescope due to launch in 2018. The objective is to ensure the astronomical community can fully exploit the enormous new science potential of JWST from day one.
Dr. Sembach has been deeply involved in the scientific, operational, and managerial aspects of the Hubble Space Telescope for the past 15 years. He has served as interim deputy director, Hubble mission head, and Hubble project scientist. Previously, Sembach was the Far Ultraviolet Spectroscopic Explorer (FUSE) deputy project scientist for Large Science Programs from 1996 to 2001 at the Johns Hopkins University. He also was a NASA Hubble Fellow from 1992 to 1995 at the Massachusetts Institute of Technology. Sembach received a B.A. in physics with honors in 1988 from the University of Chicago and a Ph.D. in astronomy in 1992 from the University of Wisconsin-Madison.
