I am a climate scientist based in the Climate Change Research Centre. My interests are very broad. I mostly work on land surface processes and how these can be represented in global and regional climate models. This includes work on limits to how well climate models represent key land processes and the implications of these limits to the reliability of projections of carbon and water in the Earth System. I'm also interested in the robustness of global and regional model projections in general, and the appropriate use of these models at various scales. 

I've recently begun to work with risk assessment processes - these use regional and global projections of future climate. I've collaborated with a range of people to try to inform business to prevent the misuse of climate projections. This includes the need to operationalise climate projections and build services that emply knowledge brokers to link business need with the information content available from models. 

I was the Director of the ARC Centre of Excellence for Climate Extremes which ended in Decembter 2025. This enabled me to collaborate with a large number of superb researchers. I am a Fellow of the Australian Academy of Science and currently Chair of the National Commitee for Earth System Science. The National Committee has been active in developing a strategic plan for our discipline. I am also on the Advisory Board of the Australian Community and Earth System Simulator National Research Infrastuture (ACCESS NRI), the science advisory board of the Terrestrial Ecosystem Research Network (TERN) and the Advisroy Board of the National Environmental Science Program (NESP) Climate Systems Hub. 

I am a Commissioner on the New South Wales Net Zero Commission. I am also a non-executive director of Risk Frontiers, an insurance funded business focussed on risk.
