My research aims to identify and understand the population of galaxies known as AGN or Active Galactic Nuclei.  These galaxies contain supermassive black holes in their centers with masses between a million and a billion times that of the Sun.  It is now thought that all galaxies contain supermassive black holes and that periods of black hole growth mark the “AGN” phase for a galaxy.  By identifying AGN in deep galaxy surveys, we can trace the growth of supermassive black holes and their effects on their host galaxies over the past several billion years.
