Personal profile
Biography
My research focuses on key physical processes in the weather and climate system and how they respond to different external forcings and background climate states. I combine a strong understanding of complex ocean–atmosphere interactions with expertise in climate modelling and experience handling very large datasets.
In my current work at ANU, I examine the temporal clustering of heavy rainfall events as part of a NESP project that aims to develop new methods to identify, measure, and map high-impact compound rainfall events. By working closely with stakeholders, I help design indices and analytical tools that support climate risk assessment, planning, and resilience building.
I completed my PhD at the University of New South Wales, where I investigated the roles of radiative processes and large-scale atmospheric circulation in Arctic amplification in warmer-than-present climate conditions, using climate models of varying complexity. This work provided new insight into radiative feedbacks that are often poorly represented in current climate models. I then held a postdoctoral position at the University of Cambridge, where I examined how clusters of volcanic eruptions affect the long-term response of the Atlantic Meridional Overturning Circulation across different background climate states.
