Research

My research is aimed at investigating the physics, structure and environment of active galactic nuclei (AGN) and improving supermassive black hole mass measurements by investigating the structure of the broad line region via reverberation mapping and by examining variability in quasar outflows/winds. Much of my previous work, including my dissertation, was on the technique of reverberation mapping, which uses AGN variability to probe the structure of the region from which we see broad emission lines; I have planned and carried out three major reverberation mapping campaigns based at MDM Observatory on Kitt Peak, am involved in a reverberation mapping campaign using the Hubble Space Telescope, as well as the Sloan Digital Sky Survey Reverberation Mapping Project, a long-term multi-object reverberation mapping campaign carried out via SDSS.  

I also carry out investigations of broad absorption line variability in Sloan Digital Sky Survey quasars; however, I am primarily working on the Sloan Digital Sky Survey Reverberation Mapping Project. While my experience is primarily in optical spectroscopic observations, I also have experience and interest in working with X-ray and NIR data as well (see some publicity on my previous work using archival Chandra data!).

I have recently joined the NIRCam team at the University of Arizona, where I am contributing to observing preparations for the extragalactic GTO program of Prof. Marcia Rieke.
