I am a theoretical physicist with interest in cosmology, gravitational physics and quantum effective field theories, the dominant modern tool of theoretical physics. In the past I have worked on developing theoretical models of the early Universe, inflation, non-Gaussianities and Initial Conditions in cosmological perturbations, braneworld models and extra dimensions and related Galileon theories.  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. In particular I am one of the developers of ghost-free massive gravity. I am broadly interested in the application of the concepts of Effective Quantum Field Theory techniques to gravity and cosmology in general, and their interplay with the possibility of UV completion.
