I'm a theoretical cosmologist at the Kavli Institute for Cosmology, Cambridge (KICC), and the Cavendish Laboratory Astrophysics Group at the University of Cambridge. My research is focused on gravitational theory and quantum gravity, including alternatives to Einstein's general theory of relativity. Gravity is perhaps the most enigmatic of the four forces of Nature, and our best theory of gravity seems stubbornly classical. The other three forces (strong, weak and electromagnetic) are healthy quantum theories which comprise the standard model of particle physics. The effects of gravity are mostly apparent at large scales, such as are found in cosmology: motivating study of the history and structure of the Universe. The armillary sphere of Antonio Santucci represents a 16th century understanding of this structure, which has since evolved via minor revisions to the current Lambda-cold dark matter (LCDM) concordance model. Antonio's craftwork is as beautiful as LCDM, so I've included my other photos of the sphere in other pages.
I'm also currently the Rosamund Chambers Junior Research Fellow in Astrophysics at Girton College, Cambridge. I was based at Wolfson College for my Ph.D., and Queens' College for my undergraduate and master's in (physical) Natural Sciences. I grew up in Cornwall, which is the south-western tip of England. At the moment I'm dividing my time between Cambridge and the Lorentz Institute at Leiden University. I also work with researchers at CEICO in Prague.
The colourful image behind this text (courtesy of the ESA and Planck Collaboration) shows the polarised microwave sky, as dominated by the magnetised, dusty foreground of the milky way which lies along the equatorial plane. Behind it lies the fainter cosmic microwave background (CMB), a far more interesting signal from the early Universe and one of the very few ways we have to observationally test quantum gravity.
