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.

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. 


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!


I am currently funded by a personal Royal Society University Research Fellowship.

Previously I was a lead author and `named postdoc' for the successful inflationary cosmology section of the Astronomy Unit's STFC consolidated grants, 2011 and 2014. 

As an `international advisor' I also co-authored with PI Nelson Nunes an `Explorations 2013' Portuguese grant application. The project was successful, and included funds for regular visits to Lisbon.


My talks

I regularly speak in support of my research giving seminars and conference talks, a list of recent presentations is in my CV, found at my  personal website.

Some online talks hosted on external sites (videos or slides) can be found at these links:

COSMO 13 (Cambridge, 2013) [Slides]

Perturbations post planck, (Helsinki, 2013) [Slides]

Perimeter seminar, (Perimeter Institute, Canada, 2013)  [Slides and video]

COSMO 11 (Porto, 2011) [Session page (my talk is fifth with slides and video available)]

Inflation +25, (Paris, 2006) [Video]


This is not an exhaustive list and I would be happy to discuss other project possibilities.
