  • Qualifications

    PhD in Science, University of Adelaide, conferred 2008.

  • Teaching Interests

    Honours, MSc and PhD research positions are available in a range of cutting-edge topics including ecosystem measurement and monitoring (carbon, vegetation structure, species diversity), biodiversity mapping and community ecology in conjunction with the Terrestrial Ecosystem Research Network (TERN).

  • Research Interests

    Landscape ecology and monitoring of Australian terrestrial ecosystems

    Some examples of my recent research:

    – Detection of large scale ecological transitions along bioclimatic gradients across Australia

    – Influence of exotic species on vegetation composition, structure and function

    – Testing relationships between the diversity of above-ground plants and that of invertebrate fauna as well as floral, faunal and bacterial diversity measured from soil eDNA

    – Influence of climatic changes through time and space on plant communities

    – Continental-scale patterns in vegetation structure and function

    – Mapping centres of biodiversity from large survey datasets 


    Systematic Botany

    I also have continuing research interests in the taxonomy of the plant family Lamiaceae including the description of new Western Australian speces in Hemigenia, Microcorys and Westringia and the evolution of floral morphology.
