Wormholes have long been a source of interest in general relativity, having been first coined by John Wheeler in 1957. More recently, wormholes have proven instrumental to our understanding of quantum gravity, with particular interest being given to Euclidean wormholes and their relevance to the gravitational path integral. However, the role of Lorentzian wormholes and their realization in our universe has remained an open question. In this thesis, I apply a modification of the Gao-Jafferis-Wall mechanism for traversable wormholes in order to construct a wormhole in the four-dimensional, asymptotically flat Kerr spacetime. To that end, I discuss the nature of quantization and field theories in curved spacetimes and their impact on this construction. With a new deformation to the action, I show that the average null energy across the throat of the wormhole is negative, rendering it amenable to information transfer while preserving the achronal averaged null energy condition.
