Roseanna completed her undergraduate in mathematics and physics at the University of Tasmania before moving to Melbourne to earn a graduate diploma in meteorology with the Bureau of Meteorology in 2013. She then spent three years as a BoM weather forecaster based in Adelaide. ​Roseanna returned to Melbourne to start her PhD in early 2017.

Roseanna's research interests focus on understanding how the changes to circulation patterns in the upper atmosphere as a result of global warming affect the changes in seasonal climate extremes experienced across Australia. ​It is hoped a better understanding of the response of these climate extremes to global warming will lead to better prediction into the future.
