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 postdoc at the University of Oxford. Prior to that, I finished my PhD in 2012 on the growth and co-evolution of black holes and galaxies over 8 billion years of cosmic time (advisor Meg Urry.)

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 and Sloan Digital Sky Survey data. I use parametric methods such as GALFIT to analyze galaxy light profiles and separate galaxies from their central active galactic nuclei (AGN), and have created my own method to determine bolometric luminosities of obscured AGN.

I am also a Galaxy Zoo scientist. Galaxy Zoo is a highly productive, highly cited project that mobilizes the public to visually classify galaxies, using the rich data produced to study galaxy evolution.
