Profile

I'm a Reader in Theoretical Cosmology at Queen Mary University of London. My main research interest is theoretical cosmology, in particular cosmological perturbation theory at linear order and beyond.


I finished my PhD at the University of Portsmouth in 2000, followed by postdocs at the IAP in Paris as a Marie-Curie Fellow and the University of Lancaster. I joined Queen Mary University of London in 2007. I have degree in Aerospace Engineering from the University of Stuttgart and a BSc in Mathematical Physics from the University of Sussex.

Undergraduate Teaching

I am teaching SPA7028U Advanced Cosmology in Semester B.

Postgraduate Teaching

I am teaching SPA7028P Advanced Cosmology in Semester B.

Research

Research Interests:

The main focus of my research is cosmological perturbation theory. My work these days focuses mainly on non-linear and second-order perturbation theory, but besides that I am also interested in inflationary cosmology, large scale structure formation, and early universe physics. I have also worked on preheating, primordial black holes, braneworld models, and instabilities in astrophysical fluids.

Supervision

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

Project Title

Frontiers of Precision Cosmology

Modern observational cosmology is built around a model of the universe that includes linear perturbations around an otherwise spatially homogeneous and isotropic background. In order to gain the maximum possible benefit from current and future observations, however, it will be necessary to understand and use second and higher-order perturbation theory. For more details click here .

Early Universe Physics

In the standard model of modern cosmology the very early universe underwent a period of extremely rapid expansion, known as inflation. This period of expansion provides the initial conditions that are necessary to explain the temperature fluctuations in the Cosmic Microwave Background, as well as the seeds of structures that later grow to become galaxies and clusters.

Public Engagement

I enjoy outreach activities.

Recently I published the popular cosmology book, together with Prof. David Matravers,

"How Cosmologists Explain the Universe to Friends and Family"

(published by Springer in 2019).
