The meeting will aim to introduce and review current understanding of extra-dimensional models, focusing on gravitational interactions and black holes. An introduction to these scenarios, will be followed by a review of the status and current challenges in describing these phenomena - from numerical GR and particle physics Monte-Carlo perspectives. Astrophysical and cosmological considerations place bounds on these processes - their impact on the models will be discussed. These scenarios have a wealth of potential phenomenology and have recently garnered much interest, with progress in both transplanckian 'quantum black holes' and rotating black holes and new tools to investigate such phenomena. Additionally, the experimental outlook will be presented.
