This thesis will be an exploration of various topics within low dimensional quantum gravity,with an emphasis on the gravitational path integral. We begin by studying two-dimensional
Jackiw-Teitelboim (JT) gravity deformed by a gas of conical defects and we solve the model
non-perturbatively. We then consider the problem of defining the Lorentzian gravity path
integral through a contour rotation of the Euclidean path integral within the context of JT
gravity. We demonstrate the agreement of integration domains and calculate the measure
for the Lorentzian path integral. We then analyze ensemble averaging a family of two
dimensional Conformal Field Theories and find a relation with an exotic three-dimensional
bulk Chern-Simons theory.
