In this talk, I will present recent results about gravitational wave cosmology. I will argue that the spatial clustering of gravitational wave sources, when cross-correlated with galaxy catalogues, provides a wealth of invaluable information concerning the origin of binary black holes and the cosmic propagation law of gravitational waves. The former will be used to distinguish between the stellar and primordial origin of the observed black hole binaries. The latter is important for constraining deviations from General Relativity on cosmological scales. Time permitting, I will also summarize our recent progress made in the field of primordial gravitational waves and the implications for the inflationary models.
