|My research interests are in general relativity, cosmology and quantum gravity. I am a member of the editorial board of Classical and Quantum Gravity, an IUPAP representative on the committee of the International Society on General Relativity and Gravitation, and Vice-President of the New Zealand Institute of Physics.|
Amongst the permanent faculty in theoretical physics my research interests most closely intersect with those of Jenni Adams and Chris Gordon.
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 currently supervise two PhD students: Yongzhuang Li and Asta Heinesen. Some recent postdocs in our group, who have now moved on, were Teppo Mattsson and Ishwaree Neupane. Emeritus Professor Roy Kerr was an active member of our group until a recent move to Tauranga. We have on-going interactions with Thomas Buchert's group at the Université de Lyon 1, and Matt Visser's group at Victoria University of Wellington.
