Two example AGN+host galaxies observed with HST and separated into galaxy and central nuclear source.

High-resolution Hubble Space Telescope images allow for decomposition of AGN and host galaxy at z~1. (Simmons et al. 2011)

I'm currently a graduate student working with Meg Urry, defending my PhD in the spring of 2012.

My primary research focus is on the connection between the growth of supermassive black holes and their host galaxies. I make extensive use of Hubble Space Telescope data, assessing correlations between host galaxy morphology and AGN activity as well as the role a growing black hole plays in regulating star formation in its host galaxy.

My thesis papers include a set of over 50,000 AGN+host galaxy simulations assessing the limits of two-dimensional image decomposition and the accuracy of recovered morphological parameters such as galaxy size, light profile, and AGN-to-host luminosity ratio.

Recently, I found that moderate-luminosity z ~ 1 growing black holes are typically in a slow-growth phase, and that many of these black holes are hosted in galaxies with strong disk components, implying the black holes are not fed by major mergers.
