A key period in our story of structure formation is the Epoch of Reionization (EoR), when early populations of galaxies and/or quasars formed, emitted ultratviolet light and ionized ' bubble' of hydrogen gas around them. These ionized bubbles grew, merged and eventually filled the entire volume of the intergalactic medium (IGM). A confluence of data sets from a variety of wavebands promise significant observational advances on this frontier topic, fueling a revolution in our understanding of cosmic reionization over the next few years. Extracting information about reionization from these observations will, however, require comparision with detailed theoretical models. Towards this end, I will describe recent efforts to theoretically model the EoR. I will then discuss what we may learn from future observations aimed at detecting 21 cm emission from the high redshift IGM.
