Current Research:

The main focus of my research is the study of Active Galactic Nuclei (AGN) in the near and distant universe.   AGN are centers of galaxies containing supermassive black holes (BH) that are actively accreting matter at relatively high rates.   Much of the gravitational energy of the infalling material is transformed into radiative energy across the electromagnetic spectrum, making AGN some of the most powerful and luminous objects in the universe.   There are many outstanding fundamental questions regarding the origins and astrophysics of AGN, such as determining the most common triggering mechanisms, the duty cycle, and the mass of the central BH.   I investigate these topics through the detailed study of the environments and host galaxies of AGN, as well as establishing relationships between observable parameters in the host galaxies and fundamental parameters in their active nuclei.

Research Interests:

  • Astrophysics
  • Observational Extragalactic Astrophysics
  • Active Galactic Nuclei
  • Quasar host galaxies and their environments
  • Ultraluminous Infrared Galaxies (ULIGs)
  • Galaxy interactions and mergers
  • Modeling stellar populations
  • Old galaxies at high redshift
  • Adaptive Optics
