In this talk, I will give an essentially self-contained introduction to the moduli space
of Calabi Yau manifolds (CY moduli). The Weil-Petersson metric on the moduli space
plays an important role. I will begin with the local theory, and use the local theory to study
the global geometry of the moduli space. I will emphasize on the Gauss-Bonnet theorem,
Chern numbers, etc, on CY moduli. The upshot is, even though we don't know the degenerations
of CY manifolds, we are still able to define these topological invariants on the moduli space.
