We study three aspects of gauge-gravity duality. First, we explore holographic models of
conformal field theories with boundary by way of holographic renormalization group flows.
Second, we propose an extension and application of the covariant holographic entangelement
entropy proposal to warped anti-de-Sitter spacetimes. Third, we exhibit the existence of
higher-spin black holes with Lifshitz asymptotics in the Chern-Simons formulation of higher
