Research Overview

I am interested in modified gravity, particularly infinite derivative gravity which may be able to resolve singularities at the centre of black holes and at the Big Bang.

I have worked on testing modified gravity through data from both laboratory experiments and from the Cosmic Microwave Background, as well as other aspects of the theory. I am currently working on generalising results found around flat background spacetimes to more general expanding backgrounds.
