I am a Professor
of Theoretical Physics.

My research interests are in general relativity, cosmology and quantum gravity. I have served on the committee of the International Society on General Relativity and Gravitation 2017-2022, and am a past President of the Australasian Society for General Relativity and Gravitation and a past President of the New Zealand Institute of Physics. I served 8 years on the editorial board of Classical and Quantum Gravity, 2012-2019. |
Amongst the permanent faculty at Canterbury my research interests most closely intersect with those of Chris Stevens in Mathematics, and also with Jenni Adams and Chris Gordon here in Physics.
My research is currently focused on understanding gravitational energy in an inhomogeneous universe: it is my thesis that is the key to understanding the mystery of "dark energy". I have a viable alternative to the standard cosmology, without dark energy, which I have named the timescape cosmology. In the past I have been Principal Investigator on two Marsden grants. I have supervised 9 completed PhDs. I am currently supervising 4 PhD students, Marco Galoppo, Chris Harvey-Hawes, Morag Hills and Michael Williams. Past postdocs in our group were Teppo Mattsson and Ishwaree Neupane. Emeritus Professor Roy Kerr participates in our group meetings. We have on-going collaborations with Thomas Buchert's group at the Université de Lyon 1, Hayley Macpherson at the University of Chicago, Krzysztof Bolejko at the University of Tasmania and Jan Ostrowski at the National Centre for Nuclear Research, Warsaw.
