Biography
I have a broad research interest in biogeography and landscape ecology in relation to climate variability and fire regimes. I am particularly interested in utilising dendrochronology (tree ring) techniques to understand past climates and fire regimes of arid and semi-arid regions in Western Australia. I also have an ongoing interest in improving understanding of the interactions between climate and fire and vegetation, topography and ecosystem processes.
Funding overview
2015 A drought atlas for Western Australia from tree rings, Research Collaboration Award, The University of Western Australia
2014 ITRAX measurements of tree ring density and chemistry to reconstruct past rainfall patterns in NW Australia, Australian Institute of Nuclear Science and Engineering (AINSE) research award

Current projects
My current research is focused on reconstructing past rainfall variability of the Pilbara region in north-west Australia and the wheatbelt region of southwest Australia using the width and stable isotope composition of growth rings of Callitris columellaris trees.
