Title of your presentation : Detecting the Rise and Fall of 21 cm Fluctuations

I will describe theoretical models of the Epoch of Reionization
(EoR). I will then forecast the sensitivity with which first generation 21
cm surveys, such as the Murchison Widefield Array (MWA), can measure
the 21 cm power spectrum. The MWA will be sensitive to roughly a
decade in scale, with foreground contamination precluding measurements
on large scales, and thermal detector noise limiting the small scale
sensitivity. This amounts primarily to constraints on the slope and
amplitude of the 21 cm power spectrum on the scales
probed. Nonetheless, I will show that the redshift evolution in these
quantities can yield important information about
reionization. Finally, I will discuss novel approaches for analyzing
the highly non-Gaussian 21 cm signal during reionization.
