    I will discuss an ongoing project to better understand quasars from the Sloan Digital Sky Survey (SDSS) by using cross correlations with BOSS galaxies that overlap in volume. We have the current best constraints showing quasar clustering does not appear to be dependent on the quasar luminosity, completely unlike what is seen with galaxies. I will also describe how we are using these measurements to further understand quasar properties, such as how they occupy dark matter halos and if their environment can provide clues on their formation and evolution.
