Joel Green headshot

Dr. Joel Green studies the processes that influence the formation of protoplanetary disks and envelopes, and the environs of young stars. He is particularly focused on outbursting young stars, accretion processes, shocks, and tracers thereof in IR, X-ray, and submillimeter regimes, and signposts of these processes in our own solar system. He is the lead of several Herschel, SOFIA, and ground-based general observer programs, including a Herschel user-provided data product archive, and a collaborator in numerous initiatives with JWST. Joel is the User Support Lead and Instrument Scientist for Hubble’s Wide Field Camera 3 (WFC3) instrument, working on pipeline calibration and characterization of detector artifacts. Joel has numerous years of experience in infrared and sub millimeter spectroscopy, developing software for creating and fitting Spitzer and Herschel data cubes. He was previously Project Scientist in the Office of Public Outreach, where he acted as liasion to the science staff, coordinating efforts in emerging tech and web development, and communication/outreach strategy for STScI with the Hubble, Webb, and Roman Space Telescopes. Joel has written for and appeared in numerous public outreach, communications, and educational materials, most recently the National Geographic special on Hubble's Amazing Universe, and PBS Nova's special on Treasures of the Earth: Metals.
