I will present techniques for extracting cosmological information from galaxy clustering at non-linear scales. These scales are usually avoided in favor of clustering measures at the largest scales where linear theory is applicable, but at the cost of measurement precision. New advances in galaxy bias make it possible not only to model the galaxy distribution at small scales, but the use these observations to strengthen our cosmological probes from galaxy clustering. In my talk I will present results from two such measures:
(1) the galaxy content of galaxy clusters, and (2) redshift-space anisotropies. I will show results from the recently completed SDSS-II redshift survey as well as preliminary results from the ongoing BOSS survey.
