Role
Senior Research Scientist, Leader of AIMS Long-term Monitoring Program for coral reefs of the Great Barrier Reef
Background
I trained as a behavioural ecologist working on reef fishes and have worked on the GBR and in the Caribbean (Panama). My research interests have broadened to processes of disturbance and recovery on reefs, particularly as applied to the GBR. After graduating, I worked briefly at University of Sydney, then spent three years as a post-doc at the Smithsonian Tropical Research Institute in Panama. From 1990 I was a post-doc at James Cook University, initially studying fish predators of Acanthaster planci, then the effects of feeding fishes around Tourist pontoons (Reef CRC). In 1995 I came to AIMS to lead the Long-term Monitoring Program.
Education
  • 1985 PhD Macquarie University, Sydney
  • 1975 BA Zoology, Oxford University, UK
Current Research Activities
Through my involvement with a large monitoring program on GBR reefs, I am interested in the status of GBR reefs and in coral reef ecology generally, especially:
  • the effects of disturbances on reef communities and processes of subsequent recovery.
  • the ecology of Acanthaster planci, the crown-of-thorns starfish, which has been the major cause of losses of living coral on the GBR in recent decades
  • "ecosystem health" particularly as applied to coral reefs
  • the effects of marine reserves.
