Environmental change can dramatically affect species, which can, in turn, trigger a cascade of effects through an ecosystem. My research is on global change biology—studying the responses of species and ecosystems to human-induced and natural environmental change.

I joined the Global Ecology Lab at Flinders University and the Centre of Excellence for Australian Biodiversity as a postdoctoral research fellow in October 2018. I am studying ancient species extinctions, using ecological network modelling to investigate their causes and consequences.

From 2017 to 2018 I worked as a Predictive Analyst and Teaching Quality Data Specialist at James Cook University. Before this, I was a postdoctoral research fellow at James Cook University and CSIRO Townsville, where my project investigated how species adjust to different climates through adaptation and phenotypic plasticity.
