Constraining Reionization with Current and Future Datasets

The study of dark ages and reionization is of immense importance in cosmology since they are directly related to the formation of first large scale structures. Research in this area received a big boost due to availability of a variety of observational data accumulated over the past few years with additional progresses expected soon from a number of different experiments. In this talk, I will present a theoretical model of reionization which accounts for most of the relevant physical processes and can be compared with a variety of data sets. I will discuss the current constraints on reionization based on this model and also talk about future prospects in this area.
