Teaching

My teaching

This year I am lecturing SPA7005 Cosmology.

I also contribute to teaching at Queen Mary by supervising astrophysics MSc and MSci students for their research projects, and I regularly work with and supervise PhD students.

In the past I have supervised in Cambridge and taught classes at Imperial and Queen Mary in a wide range of subjects including Cosmology, General Relativity, Quantum Mechanics, C++ computing and differential equations. I have also lectured on theoretical physics and cosmology at Queen Mary and for the Cambridge Institute of Continuing Education. 

Outreach

I enjoy outreach work a lot. I regularly lecture to visiting students at Queen Mary, and visit schools myself to gives talks. I also take part in various other outreach activities. More information is in my CV available at my personal website. If you'd like me to give a talk or take part in an outreach activity please get in touch!

Research

Research Interests:

My research interests

I am a theoretical cosmologist.

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.

I maintain a personal website which has more information about me and my research, including a fairly up to date CV. Information about a code for inflationary cosmology, PyTransport, that I have developed can be found at another site transportmethod.com.
