Professor and ARC Future Fellow, Macquarie University

My current research concentrates observational and theoretical work on close evolved binaries.

In particular I work on planetary nebulae and their central stars, and the hypothesis that a large fraction of them may be the result of binary interactions.

I also work on the common envelope interaction that happens when a growing star swallows its companion. These interactions give rise to scores of close, evolved binaries and mergers.
