Andrew Tolley

Research Interests

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. I am particularly interested in exploring the implications of String Theory, Branes and Extra Dimensions for Cosmology, as well as Models of Dark Energy, in particular those arising from Infrared Modifications of Gravity, and the associated Cosmological Constant Problem.
