My research focuses on the late Quaternary fossil record of arid and semi-arid Australia, with an emphasis on how meaningful ecological inference can be drawn from records that are inherently sparse and unevenly distributed.

​

Much of my work centres on stick-nest rat (Leporillus) rodent middens, which preserve plant macrofossils in arid environments where other palaeoecological archives are rare. I began working with these records to better understand large discrepancies in the spatial and temporal distribution of the midden fossil record.

​

I am particularly interested in how quantitative, model-based approaches can be used both to interpret the limited information preserved in existing midden records and to identify where additional records are most likely to be found.
