21cm cosmology is a new and exciting area of research with a great deal of potential. We have now entered an era of precision cosmology, but almost all of the information used to achieve this precision has come from the CMB at redshift z ~ 1100 or from galaxy surveys below z ~ 1.5. Using observations of the redshifted 21 cm line of atomic hydrogen (HI) we can look at previously unexplored epochs, like the Dark Ages and the Epoch of Reionization (EoR), as well as complement (and compete with) the results from galaxy surveys at low redshifts. In this talk I will present recent work on Weak Lensing studies using 21-cm radiation from the EoR as well as from a post-reionization "intermediate" redshift range (2
