Patrick is an observational astronomer specializing in infrared, optical, and X-ray spectroscopy of active galaxies and quasars. He is an instrument scientist on the JWST NIRSpec Team, and previously worked on the Chandra HETGS, XMM-Newton OM, and Spitzer IRS instrument teams, and the NASA Extragalactic Database. He studies quasar accretion, jets, and outflows, and their effects on galaxy evolution. He recently discovered a new class of very massive and luminous spiral galaxies, called super spirals.
