As of the 26th of September 2016, Daniel Mortlock will be associated with the Department of Astronomy as a guest researcher for 30 % of his time.  Daniel is a lecturer in astro-statistics at Imperial College, London and specialises in statistical methods for large astronomical data sets, specifically Bayesian methods. Using such methods he led the discovery of the most distant known quasar, ULAS J112001.48+064124.3, which with a cosmological redshift of 7.1 dates from the time when the Universe was only 750 million years old. In Stockholm Daniel will be working on other astronomical applications of such statistical methods and he will also be teaching the new MSc level course Bayesian Statistics For Astronomers And Physicists.
