Today there are multiple large surveys with photometric and spectroscopic measurements of many millions of extragalactic objects. However, redshift information is available for only a fraction of these objects. I am using new techniques for inferring distance information using the fact that the universe is not uniform and galaxies are clustered. The aim is to improve the infrared and radio luminosity function measurements. This is of interest as it traces the cosmic stellar mass growth and star formation history and therefore gives us insight into galaxy formation and evolution. As most of the objects in this wavelength regimes don't have spectroscopic redshifts we need different approaches to estimate their redshift. This is where the clustering redshift method comes in.
