  • Qualifications

    PhD in Science, University of Adelaide, conferred 2008.

  • Teaching Interests

    Honours and PhD/post-graduate research projects are available in topics such as ecosystem measurement and monitoring (carbon, vegetation structure, species diversity), biodiversity mapping, community ecology and functional ecology in conjunction with the Terrestrial Ecosystem Research Network (TERN).


  • Research Interests

    Influence of environmental change on ecosystem properties and biodiversity assets

    My work within the Terrestrial Ecosystem Research Network (TERN: AusPlots/ATN) includes:


    1) Overseeing ecological monitoring activities along the TREND transect.


    2) Analysis of ecosystem transitions and climate sensitivity in South Australia and across Australia.


    3) Devloping derived data products from raw data collected by TERN.  


    4) Continental-scale analysis of Australian ecosystems (such as patterns of biodiversity, and vegetation type, structure, cover and composition) to map ecological assets and their vulnerability to climate change and other disturbances.
