Interests

I'm interested in all aspects of the structure and evolution of the universe, from its earliest moments to its behaviour today, and in observations which inform us about the universe. Predominantly, however, I have worked on the very early universe, and in particular a phase of accelerated expansion known as inflation. Inflation is thought to be the origin of all structure in the universe, and so is a hugely important period in its history.
