"In this thesis we investigate the feasibility and phenomenology of transplanckian field displacements\r\nduring Inflation as well as the production of very light fields during Reheating.\r\nWe begin by focusing on realisations of axion inflation in the complex structure moduli\r\nsector of Type IIB String Theory (ST) flux compactifications. Firstly, we analyse the problem\r\nof backreaction of complex structure moduli on the inflationary trajectory in a concrete model\r\nof axion monodromy inflation. Secondly, we propose a realisation of natural inflation where the\r\ninflaton arises as a combination of two axions. In both cases we find sufficiently flat inflationary\r\npotentials over a limited, but transplanckian field range. However, our realisation of axion\r\nmonodromy inflation requires a potentially large, though realisable, number of tunings to ensure\r\nthat the inflationary shift symmetry is only weakly broken.\r\nThe consequences of the Weak Gravity Conjecture (WGC) for axion monodromy inflation\r\nare then explored. We find that the conjecture provides a bound on the inflationary field range,\r\nbut does not forbid transplanckian displacements. Moreover, we provide a strategy to generalise\r\nthe WGC to general p-form gauge theories in ST.\r\nFinally, we focus on the physics of the early post-inflationary phase. We show that axion\r\nmonodromy inflation can lead to a phase decomposition, followed by the radiation of potentially\r\ndetectable gravitational waves. We also propose a strategy to evade the overproduction of Dark\r\nRadiation in the Large Volume Scenario of moduli stabilisation, by means of flavour branes\r\nwrapping the bulk cycle of the compactification manifold."^^ .
