My research is on supermassive black holes, active galactic nuclei (AGN), and galaxy mergers.  In particular I study AGN feeding and feedback, which includes AGN activation during galaxy mergers and AGN outflows influencing star formation in their host galaxies.  To carry out this work, I use a suite of ground-based (APO, Keck, VLA) and space-based (Chandra, Hubble, WISE) telescopes.
