Nested sampling is an MCMC technique for integrating and exploring probability distributions. It has become widely adopted in the field of cosmology as a powerful tool for computing Bayesian evidences and sampling challenging a-priori unknown parameter spaces.

In this talk, I will give an introduction to the principles of Bayesian model comparison and parameter estimation, an explanation of the theory of nested sampling, a survey of the current state-of-the art (MultiNest, PolyChord, DNest and Dynesty) and the future of the field. I will illustrate with applications in CMB and 21cm Cosmology, Bayesian Sparse Reconstruction and Bayesian Neural Networks.
