Dr Sophie Lewis

Honorary Senior Lecturer
ANU Institute for Climate, Energy & Disaster Solutions

I am a climate scientist interested in understanding climate change and variability, in the past, present and future.

I completed my PhD in 2011 investigating long-term changes in the Australian monsoon system. Since then, I have worked as a postdoctoral research fellow at the University of Melbourne and the ANU investigating the causes of recent extreme climate events in Australia.

I'm currently working on several research projects focusing on the attribution of extreme climate events, the evaluation of climate models and reconstructing past climatic change.
