Research Scientist

I have joined the research team at Phillip Island Nature Parks to continue my research into marine predator demography and ecology. I have spent the last 12 years working on various species of seals in Australian waters, including Macquarie Island in the sub-Antarctic and the islands of South Australia. Recent roles have included being a research consultant and a Senior Research Scientist at South Australian Research and Development Institute – Aquatic Sciences, South Australia. Much of my work has involved studying the life history and demography of the Australian sea lion. My areas of interest also extend into marine protected species management, conservation and avian biology.

At Phillip Island, my research focusses on Australian fur seals and Little penguins. For the Australian fur seal I am monitoring population trends, entanglement rates in marine debris and diet. Using the Little penguin, I am exploring novel approaches to cleaning seabirds that have been impacted by oil spilt at sea. An extension of my research will involve ecosystem trophodynamics and food web analysis.

I am an Honorary Associate of La Trobe University and a member of the Australian Marine Science Association and the Society for Marine Mammalogy.
