Current Research:

I am currently leading research programs in three broad areas of astrophysics. One is the discovery and analysis of obscured/red quasars to understand their relationships to the early stages of quasar/galaxy evolution. Another focuses on quasar accretion disk outflows to understand the origins, energetics and physical properties of these flows and test their viability as a feedback mechanism that could regulate star formation and mass assembly in the host galaxies. A third employs quasar absorption lines to measure the full range of gaseous environments around quasars and derive further constraints on nature and evolutionary status of quasars in their host galaxies. The absorption line environments include quasar-driven outflows, ambient gas in galactic halos, remnants from recent messy mergers, starburst-driven blowouts that might accompanying quasar activity, and infall (“cold mode accretion”) from the inter-galactic medium that could be critical for galaxy assembly. These studies use numerical simulations and data from major observatories including the Hubble Space Telescope, the Chandra X-ray Observatory, the Atacama Large Millimeter (and sub-millimeter) Array, large ground-based facilities such as Keck, Gemini and the VLT, and wide-field surveys like the Sloan Digital Sky Survey (SDSS) and the Wide-field Infrared Survey Explorer (WISE).
