Modeling and observing cosmic reionization

The reionization of the intergalactic medium (IGM) is one of the last mostly unexplored frontiers is observational astrophysics. In this talk I will discuss some recent developments in the theoretical modeling of the process which will aid the interpretation of upcoming observations. I will also present prospects in the detection of the 21cm line from neutral hydrogen from the high redshift IGM and what such measurements will reveal about cosmic reionization.
