Title: Scalar mode dynamics in Horava-Lifshitz gravity

Abstract: 

 Horava-Lifshitz gravity has been proposed with the hope of being a UV complete gravity theory. After giving a brief overview of the various versions of the theory, I will focus on the dynamics of the extra scalar degree of freedom with respect to general relativity. The consistency and viability of each version depends crucially on the behaviour of this scalar mode.
