John Debes headshot

John Debes is the STIS branch manager and oversees the calibration and scientific support of the STIS instrument on the Hubble Space Telescope. He is currently a member of a Science Investigation Team for NASA's Nancy Grace Roman Space Telescope Coronagraphic Instrument. Dr. Debes joined the Institute in 2011 as an ESA/AURA Astronomer and worked on the COS/STIS team until 2016.

Prior to joining the Institute, Dr. Debes was a NASA postdoctoral fellow at the NASA/Goddard Spaceflight Center from 2008-2011 and a postdoctoral researcher at the Department of Terrestrial Magnetism, Carnegie Institute of Science from 2005-2008.

Dr. Debes studies the formation and evolution of planetary systems across various aspects of a star's lifetime. The goal of his research is to understand the mechanisms of terrestrial planet formation as well as the possible chemical abundance of a typical rocky planet. This research serves the larger goal to understand the Earth and its place within the Milky Way.
