I am a faculty member in Astrophysics at Oxford University. I'm also a Senior Research Fellow at Exeter College.
From 2006-07 I was a post-doc at Princeton University. I did my PhD in Astrophysics at Oxford, and my undergraduate degree at Cambridge University.

Research Interests:
My research is in cosmology, and I am particularly interested in the Cosmic Microwave Background (CMB), relic light that provides us with a snapshot of the early Universe. I have been involved in determining properties of the Universe such as its expansion rate, its density, and how much dark matter and dark energy there appears to be. I have also used cosmological data to test inflationary models describing the rapid expansion of the Universe in the first fraction of a second. More recently I have developed an interest in the microwave emission from the Milky Way, to learn more about properties such as the galactic magnetic field, and to insure that we can correctly distinguish between galactic and primordial light.
We have come a long way in formulating a cosmological model, but there are still important questions that I hope we will be able to answer in the coming years. These include: Is Inflation the correct description of the early Universe? What is the nature of dark energy? Is cold dark matter composed of particles, and if so what sort of particles are they?
I am currently a member of the NASA Wilkinson Microwave Anisotropy Probe (WMAP) science team, and am part of the Atacama Cosmology Telescope (ACT) collaboration.
