Research interests

I’m a Research Scientist with the Australian Antarctic Division and a Project Leader with the Antarctic Climate and Ecosystems Cooperative Research Centre (ACE CRC). My research uses mathematical models of marine ecosystems to understand how these systems function and how they might respond to climate change and other human activities. In particular, my team and I use ecosystem models to simulate different future scenarios and to help determine what’s driving change in particular components of the system. These results can then inform where and how we might best coordinate and invest in further research and monitoring.

This work is part of the Integrating Climate and Ecosystem Dynamics (ICED) program, which aims to develop a coordinated circumpolar approach to understanding climate interactions in the Southern Ocean, the implications for ecosystem dynamics, and the development of sustainable management procedures. I am particularly interested in the translation of science into decision-making.

In 2017 I was named as one of Science & Technology Australia’s 30 STEM Superstars, and was also named Tasmania’s Young Tall Poppy of the Year in 2015 for my research, science communication and policy engagement. I am passionate about encouraging greater representation of women in science leadership and was a finalist in the Women’s Agenda leadership awards for 2017. I was one of 12 women scientists to have my portrait featured as a constellation on the ceiling of New York’s Grand Central station, as part of GE’s Balance the Equation campaign.

I was awarded my PhD in Quantitative Marine Science from UTAS in 2010, and was a Rhodes Scholar at the University of Oxford from 2003-2005.
