I am a theoretical cosmologist with interests in a wide range of topics, including: Developing models of the Early Universe, Inflation, Non-Gaussianities and Initial Conditions, Braneworlds and extra dimensions. More recently my research has focused on explanations of the late time acceleration of the Universe, through developing models of Dark Energy, and Modified Gravity, and addressing some of the challenges posed by the Cosmological Constant Problem. I am interested in the application of the concepts of Effective Field Theory to cosmology, and their interplay with the possibility of UV completion.
