DESCRIPTION:I will discuss the quantization of one of the simp
 lest theories of gravity\, three-dimensional Einst
 ein gravity with negative cosmological constant. I
 n particular I will describe a precise reformulati
 on of AdS_3 quantum gravity in terms of a novel to
 pological quantum field theory known as "Virasoro 
 TQFT." This proposal clarifies the relationship be
 tween pure AdS_3 quantum gravity and (two copies o
 f) SL(2\,R) Chern-Simons theory\, and resolves som
 e well-known issues with this lore. I will argue t
 hat moreover this proposal provides a practical fr
 amework for the computation of 3d gravity partitio
 n functions\, and will describe how it elucidates 
 various aspects of the holographic dual.
