New paper and Pyflation software package

By Ian | Published: March 7, 2011

My latest paper has just hit the arXiv and is now available. The paper builds on the numerical work I previously completed on cosmological perturbations beyond linear order. The new results do not assume slow-roll in the calculation of the source term for the second order equations of motion and so allow a much greater [...]

Relativity and Cosmology Seminar

By Ian | Published: March 25, 2010

Yesterday I gave my first seminar as a postdoc in the regular Relativity and Cosmology series at QMUL. People seemed to engage with the material and there were quite a few questions at the end. The slides for the talk are available as a pdf or through the embedded widget below. My style for talks [...]

I am a theoretical cosmologist at Queen Mary, University of London. My work focuses on the early universe and in particular inflationary models.
More info and my CV

My recent work has included creating numerical simulations of cosmological perturbations during inflation. My code, called Pyflation, is open source and available for download.
