We review our recent results on holomorphic affine structures on the Teichmüller spaces of Calabi-Yau manifolds and their Hodge metric completions, as well as their applications to global Torelli theorems for Calabi-Yau manifolds. As corollaries we show that the extended period map from the completion space is injective into the period domain, and that the completion space is a domain of holomorphy and admits a complete Kähler-Einstein metric.
