Biography

I obtained my MA and MSci degrees from the University of Cambridge in 2001. I stayed at the University to study for my PhD in astrophysics at the Institute of Astronomy. After this I undertook postdoctoral research at the Institut d’Astrophysics de Paris, Queen’s University Belfast and the Institute of Astronomy. In 2011 I was appointed as a Lecturer of Astrophysics at The University of Auckland.

My research is focussed upon the lives and deaths of stars. Most of my work involves the suite of computer codes I have created, the Binary Population and Spectral Synthesis code (BPASS, bpass.auckland.ac.nz). Using BPASS I study stars in our own Galaxy to stars in the galaxies at the edge of the observable Universe.

In addition to my research activities I am also keen to participate in public understanding of science activities and have helped out at open days for previous departments. I have also given many public talks in Inverness, Chester, Antrim and Cambridge. My talks are on various subjects such as: "The Birth, Life and Death of Stars", "Stars in their death throes” and “Supernova Kicks and Runaway Stars".

Recently I have given a few talks on the topic of assessing how accurate science-fiction can be with titles such as: "The Science of Sci-Fi: The Good the Bad and the Ugly" and "The Science of Sci-Fi: does every planet look just like home?"

  • Astrophysics
  • Stellar Evolution of Single and Binary Stars
  • Supernovae
  • Gamma-ray Bursts
  • Stellar Population and Spectral Synthesis
  • High-redshift galaxies
  • Stellar origin gravitational wave transients

My research is mainly focussed upon the evolution of stars. I have created a unique Binary Population and Spectral Synthesis code (BPASS). While similar codes (such as starburst99) exist BPASS has important features, each of which set it apart from other codes and in combination make it the cutting edge. For more information see the bpass.auckland.ac.nz website. A great amount of time and effort has been invested to create BPASS. The development is now complete and it is at the centre of much of my current and future research.
