I am Professor of Polar Geodesy and Director of the ARC Australian Centre for Excellence in Antarctic Science (antarctic.org.au), based at the University of Tasmania.
My field of expertise is geodetic observation of Earth deformation and the global water cycle, including ice-sheet mass balance and sea-level change and particularly using the Global Positioning System (GPS) and the Gravity Recovery and Climate Experiment (GRACE). I also work on reduction of systematic and random errors in these techniques in order to maximize the information content in the data and improve the reliability of the interpretations.
I have authored more than 130 peer-reviewed publications including several articles in the leading scientific journals Science, Nature, Nature Geoscience, Nature Climate Change and Proceedings of the National Academy of Science.
In 2015 I was awarded the Royal Society (London) Kavli Medal and Lecture (see the lecture at https://royalsociety.org/events/2015/04/continental-loss) and in 2018 I was awarded the Mawson Medal and Lecture by the Australian Academy of Science.
