Survey synergy: combining CMB and galaxy surveys

Large scale structure (LSS) alters the appearance of both background galaxies and the cosmic microwave background (CMB) through the effect of gravitational lensing. Auto and cross-correlations of these observables provide us independent information, and the various probes can be combined to constrain cosmology. In this talk, I will present the recent results from combining SPT and DES year 1 data sets. I will also discuss what we have learnt, and the improvements we are going to make in the year 3 analysis.
