Current Research

My research fits within the wide range of studies about climate change and the environmental impacts of climate change. I am particularly interested in uncovering paleoenvironmental changes and species responses under the pressing influences of climate change. My current research aims to reconstruct climate- and fire- driven ecosystem changes across temperate and subtropical Australia. Another line of research is focused on the understanding the role of climate modes in driving fire activity across the Southern Hemisphere.
