Dr Jess Melbourne-Thomas - marine ecologist & ecosystem modeller
Scientists of the Antarctic: Dr Jess Melbourne-Thomas
I think the main thing I love about the work that I do is the challenge.
In my work I use field observations, ecosystem science and also mathematical models to understand and help manage risks for Antarctic marine biota, so particularly the effects of climate change and fisheries on Southern Ocean ecosystems.
You know these are really big questions and they’re urgent questions and I find that exciting.
The research that I do and that my group is involved with delivers into forums like CCAMLR, the Commission for the Conservation of Antarctic Marine Living Resources, to inform the decisions they make on a year to year basis around managing fisheries and the conservation of dependent species like penguins and seals.
But it also delivers into some of the more global policy environments and bodies like the IPCC which is the Intergovernmental Panel for Climate Change.
I think being in the field and experiencing the Antarctic environment is really important in terms of understanding the scale of these systems and the isolation and even just the effort that goes into collecting every piece of data that we use to inform the models. So I think that’s a really important part of being an Antarctic scientist and a modeller is to experience the environment itself.
Dr Jess Melbourne-Thomas: BSc (Hons), PhD
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.
