Research

Research Interests:

My 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.

PhD 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.

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.
