Research
My research interests lie in fundamental particle physics and its applications to cosmology. In particular the use of string theory and supergravity to explain the observed (but currently unaccounted for) late-time acceleration of the universe.
I am very interested in scalar-tensor theories of gravity that posess screening mechanisms such as the chameleon, symmetron and the environmentally dependent dilaton models. I spend a lot of my time trying to find a UV completion of these models in fundamental theories as well as looking for similar models in particle physics. I am also very interested in looking for observational signitures of these models, especially those relating to the effect they have upon stellar structure and evolution.
In the past I have worked on the modelling of hierarchical galaxy formation using semi-analytic models and N-body simulations.
